NS4379 : Ancient trackway by Lairich RigNS4377 : Ancient trackway by Lairich RigOld limestone industry tracks.

The purpose of this article is to describe and to illustrate an extensive network of old tracks traversing a large area of moorland centred on Dumbarton Muir in West Dunbartonshire. In past centuries, those tracks were employed by those working in the local limestone-burning industry. Alongside those tracks, various relics of that industry can be seen in several places; these former industrial sites are also shown and described in this article. The tracks branch off from two main routes (whose use was by no means limited to the limestone industry): the Common Drove Road, which runs from east to west; and the Old Drymen Road, which runs from SSW to NNE.

The moorland area covered by this network may now seem rather empty, but the tracks and the remains that can be seen alongside them provide a valuable record of a long-vanished industry.

At the time when the present article was first written (September 2012), a large part of the area covered by this network of tracks was threatened by a proposed wind farm development associated with Merkins FarmExternal link; that development, which was to have been centred on the Hill of Standing StonesExternal link, had not yet been approved (for the Hill of Standing Stones itself, see the section 'Other sites of interestExternal link'). However, even at that early stage, some disturbance of the moor, in the form of heavy vehicle tracks, had resulted from preliminary work, such as the erection of an anemometer mastExternal link. The application for the Merkins Wind Farm development was subsequently (23 October 2013) rejected by the Planning Committee.

Some of the individual industrial relics on this old network had already been reported (I provide links to existing reports, where appropriate). In addition, I discovered and reported several new sites, which are also included in this article.

As for the complex network of tracks as a whole, it had not been recognized before now. I have attempted to map it in some detail, having examined much of it on foot; this article serves as a record of those findings. I believe that it is important to record such traces of our industrial heritage while they survive.

A Google Map has been created to accompany this article. Many of the sites described here are marked on it, and most of the map's marker pins have thumbnail photographs associated with them, as well as links to photographs on Geograph where more detailed information can be found for the individual sites. For those who simply wish to look at the map without further preamble, see 'THE MAPExternal link' (right-click and open in a separate tab or window).

For more about the map, see the subsection 'The mapExternal link', below. In later sections of this article, links are given to the same map, but with the view automatically centred on the particular area under discussion.

For interest, and to provide some context for the system of tracks, a number of unrelated archaeological sites that happen to lie within the same area will also be discussed (see 'Other sites of interestExternal link').


The historical background

In this area, limestone that was quarried locally was burned in lime-kilns in order to produce lime for agricultural use.

Articles by John Mitchell (see [Mitchell1995] and [Mitchell2013] in the referencesExternal link) provide some valuable historical background: as explained there, the first documentary records of the limestone-burning industry in this district date from 1707. The industry was at its peak in the second half of the eighteenth century, but virtually collapsed after 1815.

The raw materials

David Ure, writing in 1794 (see [Ure] in the referencesExternal link), mentions three kinds of limestone. The first of them, which he simply calls limestone, does not appear to have been locally common; instead, Ure writes that it was "wrought in great quantities, in the parishes of Cumbernauld and E. Kilpatrick", where it was blasted out with gunpowder and then drawn out of the mine by horses. This kind of limestone was not found locally in any quantity, and the burning of it to produce lime was likewise done elsewhere; for those reasons, it need not be discussed any further in the present article.

Cornstone: The second variety is what Ure calls "moor limestone"; he says that it is found on moors and high ground, and that it has a coarse, gritty texture. He is clearly referring to what is now sometimes called cornstone; cornstone outcrops are still abundant throughout this area, and they provided much of the raw material for the local limestone-burning industry. In what follows, I will generally use a more familiar term, and refer simply to "limestone", but it is worth keeping in mind that most of this stone (except for that found in the glens) was in the form of cornstone. Ure notes that the lime produced by burning it was not quite so good as that made using the aforementioned limestone from Cumbernauld. A further disadvantage was that it tended to occur in places far from coal (which was the preferred fuel in lime-kilns). Locally, peat was employed, with some success, as an alternative fuel in the kilns; Ure describes one such effort, at Merkins Muir, in some detailExternal link.

NS4480 : Cornstone outcrop by Lairich RigNS4278 : Cornstone outcrop by Lairich RigCornstone outcrops, the "moor limestone" of Ure's 1794 report. This was one of the two kinds of limestone that were found and burned locally.

Cementstone: The third variety of limestone that Ure mentions is one that he calls "cam-stone" or "glen-stone", "because mostly found in the bottom of glens". He describes it as occurring "in thin strata imbedded in till". Although the term had probably not been coined in his day, Ure gives an accurate description of what geologists now call Ballagan Beds: in these formations, layers of cementstone occur between thicker strata of siltstone. Cementstone is an impure form of limestone, and was evidently the "cam-stone" to which Ure refers. In the area described in the present article, layers of cementstone nodules can be seen in the steep sides of the Murroch Glen and Auchenreoch Glen; these nodules gradually erode out of the crumbling slopes, and can be found in abundance in the stream beds. In connection with the burning of cementstone, Ure notes some peculiaritiesExternal link: he says that the burnt stones must be slaked in the kiln while still red-hot, or they will not "fall down" (break down) into lime. He suggests that the nodules might gradually break down on their own, without the need for burning, and that they could be put to agricultural use in that way.

(right) A cementstone nodule in the bed of the burn. Cementstone is the "cam-stone" or "glen-stone" of Ure's report, and it is the other main form of limestone that was found and burned locally.

The two main raw materials, then, were limestone (or cornstone), found in outcrops over much of the moor, and cementstone, which was found in the deep glens. The network of tracks with which the present article is concerned was mainly associated with the widespread cornstone outcrops; this material had to be quarried out and then brought to kilns for burning.

As for cementstone, it was burned in lime-kilns that were located deep down in the glens; there, the stone to be burned was near at hand, as was a source of water for slaking it afterwards. These kilns, set within the glens, do not appear to have been closely tied into the larger network of tracks, but they represent another important aspect of the same industry. I will discuss those kilns separately below, and their sites are included, in the form of dark pink markers, on my map of the network.

Vanished farmsteads

It will shortly become clear that what now seems to be empty moorland was once a scene of industry. Additionally, there were several farmsteads in the area. At the south-western end of the network is the still-extant Maryland Farm (NS41917708), and Merkins Farm (NS44038283) lies just beyond the north-eastern end. No other farms lie between them at present, but when the limestone-burning industry was at its height, there were several in that area.

The agricultural remains to be seen in the area include: Auchenreoch External link, whose ruins are still quite prominent; the meagre remains of SpoutsExternal link and of the enclosure that surrounded itExternal link; the faint remains of an unnamed farmsteadExternal link at Black Wood; the remains of a longhouseExternal link; and cultivation tracesExternal link and the remains of an enclosureExternal link at Red Brae. There was also a farmstead called Broadfield, not far from Maryland; it is shown as Breadfield on Roy's Military Survey of Scotland (1740s-50s). Its precise location is uncertainExternal link, but an enclosureExternal link near Square Wood may have been associated with it.

These vanished farmsteads will be discussed individually below, in connection with the relevant parts of the network of tracks.

The network

The map

For convenience, I have created an annotated satellite view showing the network of tracks and the many sites of interest on them. It is in the form of a Google Map:

The map: LINKExternal link (right-click and open in a separate tab or window).

Users can zoom the map view in or out, or drag the image to pan around the area of interest. The marker pins on the map often have one or more photographs associated with them: click on any of those marker pins to see thumbnail images; below the thumbnail images are links to pages on Geograph where larger versions of the pictures, and much more detailed information, can be found.

The limestone industry tracks are represented by red and blue lines on the map. The blue lines are two old roads that are shown on an early-nineteenth-century map, the "Plan of Dumbarton Muir with the Disputed Marches between the Town of Dumbarton and Mr McGoun and others" (on which, see the referencesExternal link; the course of the two old roads as shown on the Plan is described there in much more detail). For convenience, I will refer to the one running from SSW to NNE as the Old Drymen Road, and the one running from west to east as the Common Drove Road.

The local limestone-burning industry appears to have made use of those roads: many of the subsidiary tracks (which are depicted in red on my map) branch off from them, leading towards sites associated with that industry.

Without those red and blue lines, most of the tracks themselves would not be visible on the map; many of them are only apparent in satellite imagery for which the lighting was particularly favourable. As an accompaniment to my map, users of Google Earth may wish to use that program's "View"/"Historical Imagery" feature, and drag the slider to bring up satellite imagery from 2005; in that set of images, the sun's illumination was from a particularly shallow angle, making many details evident that would otherwise be invisible, or nearly so.

(Ideally, my annotated map would have been drawn on top of the 2005 images; however, there does not appear to be an option for creating a Google Map using other than the most recent imagery.)

The following sections of this article discuss individual areas of the network. At the start of each of those sections, a link is given to a centred satellite map; this is the same Google Map as given above, but with the view centred on (and zoomed in on) the relevant area.

Maryland and Broadfield

Centred satellite map: LINKExternal link

An important old track, which could be described as the backbone of this network, begins as a continuation of the present-day farm track that leads past Maryland Farm (NS41907707) and Square Wood (NS42037763). It is shown in blue on the map, and is in fact the Old Drymen Road (see below).

Maryland Farm has a long history; its name, and that of the adjacent PriestyardExternal link, are thought to indicate an association with Dumbarton's ancient Collegiate Church of St MaryExternal link, of which only fragments now remain. For more on the association implied by these names, see the link just given for Priestyard.

Near where the track passes Square Wood, there used to be another farm: Roy's Military Survey of Scotland (an important map made in the 1740s-50s) shows a farmstead here called Breadfield, standing on the NW side of the track. It is also depicted, as Broadfield, on "A Plan of the Lands of Highdykes, High Murroch & Auchinreoch Being Part of the Estate of Levenside 1801".

Broadfield was perhaps close to what is now the northern corner of Square Wood; an enclosureExternal link nearby, at NS41927781, may have been associated with that farm; a similar enclosureExternal link is located about 370 metres to the NNE, at NS42037817.

The 1801 plan includes a number of other interesting details: for example, it shows a site labelled "Belting Kiln" near the source of the Spouts Burn.

However, I also encountered some difficulties in working from that plan: specifically, when attempting to match the features shown on it to present-day topographical features (and to Roy's Military Survey), I found that I had to proceed on the assumption that what the plan labels "Little Glen" is really Glendonachy, and that what it labels "Glendonachy" is really Auchenreoch Glen. This is hardly satisfactory, and it accounts for my reluctance to be dogmatic about the location of Broadfield.

There was much activity here during the Second World War, and the area has been disturbed as a result: see Starfish decoy control bunkerExternal link and remains of Starfish decoyExternal link. Lest that sound like a complaint, it is worth noting that this decoy site helped to save Dumbarton from the kind of destruction that befell Clydebank in 1941.

(Note that a separate annotated satellite viewExternal link marks the positions of the Starfish Decoy, its control bunker, nearby bomb craters, and the older enclosures in that area; it does so in more detail than the map associated with the present article.)

There are no traces of the limestone industry along this first part of the road; it merely provided convenient access to the moors from the town of Dumbarton.

On the early-nineteenth-century "Plan of Dumbarton Muir", the road is labelled "Road to Drymen &c"; this old road to Drymen was probably used as a drove road (it was described as such by I.M.M.MacPhail in his 1976 booklet "Off the Main Road"). Another old drove road (the Common Drove Road, discussed later), crossed the moor from west to east, and is likewise shown on the "Plan of Dumbarton Muir". As the satellite map shows, the two roads, both drawn in blue, intersect in the vicinity of the Lang Dyke, near the most important concentration of limestone industry sites on the moor; more on this later.

After passing the site of the vanished farmstead of Broadfield, the Old Drymen Road runs fairly close to the upper part of Auchenreoch Glen. There are three lime-kiln ruins in the upper glen, the firstExternal link at NS42277835, the secondExternal link at NS42477847, and the thirdExternal link at NS42677865; for reasons explained above, these kilns are not closely tied into the network of tracks. However, it is at about NS42707862, near the third of those kilns (illustrated below), that the track forks. Incidentally, in "Off the Main Road", I.M.M.MacPhail mentions that, when following this track, which he describes as an old drove road, the ruins of Auchenreoch can be seen, off to the left; those ruinsExternal link are also shown on the satellite map.

The left-hand branch (discussed below, in the section 'Auchenreoch MuirExternal link') is the course of the Old Drymen Road, and leads to the northern half of the network. The right-hand branch leads, instead, to a large area of former surface quarrying, described next.

The right-hand branch of the track heads north-east to about NS43557922, at which point it crosses a small burn. The track, braided in places, is quite visible where it approaches the burn (shown below, on the left). The area on the eastern side of the burn (below, right) has a disturbed look.

(right) The disturbed and conspicuously green area just to the north.

The track then makes zigzag progress in a more or less easterly direction; it is easily visible in this area. Near its eastern end, the track fans out across several areas (e.g., NS44127914 / NS43977911 / NS43987904) where there are signs of extensive surface quarrying.

(right) The track fans out here into several areas that show clear signs of surface quarrying. One of those areas is shown here.

The depth and braiding of these tracks reveal that this was a well-used and very productive part of the network.

Black Wood

Centred satellite map: LINKExternal link

A south-eastern part of the network begins not far from present-day Garshake Farm. It is not possible to trace its route directly until the point where it becomes visible on the open moor, heading north-east from about NS42067682, but it is possible to make reasonable inferences about its beginnings: this particular route probably began on what is now the line of Garshake Road, and then continued from there to about NS41707649 by means of a route close to the road that passes through the present-day waterworks (it may have been a little to the south-east of the line of the modern road).

From there on, the course can be described with greater certainty: the old track would have continued north-eastwards, just inside the north-western edge of what is now a strip of woodland centred on NS41897665. The ruins of Upper Garshake FarmExternal link, now almost indiscernible, are therefore right alongside that old track. The farm was also known as Hill of Garshake, or (where the context ensured that there was no ambiguity) just Hill.

Beside the south-eastern edge of the same strip of woodland is a disused farm track that heads north-east from NS41727648 to NS42047678, and which is marked on the first-edition OS map (surveyed in 1860). It would be tempting to think that this is a relic of the old route, but it is not: where the old route emerges on to the open moor, it can be seen that it does not quite align with that farm track, although it does run parallel to it; it is clear that the original route was a little to the north-west of the farm track, within what is now a wooded area. It is likely that the farm track was created when the much older route fell into disuse, and when the strip of woodland was subsequently planted around it.

From NS42067682, the old track itself leaves the woods, and becomes visible on the open moor, continuing NNE as a braided track. The first part of it is obscured by treesExternal link, as shown in the pictures below:

NS4276 : Braided track in woodland by Lairich RigNS4276 : Braided track in woodland by Lairich Rig(left) Braided track in woodland; looking downhill.
(right) The same area, shown in a view uphill.

At about NS42207697, the track emerges from tree cover, but is hidden by gorseExternal link instead. From about NS42317702, the braided track is better exposed to view, and it passes some remains, as described next.

A cultivated plot:

To the west of the braided track is an area covered by a pattern of ridges and furrowsExternal link, spaced about 1.5 metres apart. The area is centred on NS42357707, and its outline is a quadrilateral, measuring 75 metres (SW-NE) by 45 metres (WNW-ESE, which is also the orientation of the ridges and furrows); this was presumably a cultivated plotExternal link.

Its appearance is typical of the kind of plot that would be found right next to a farmhouse; it would not simply occur in isolation. I was unable, though, to find any definite remains of buildings nearby. On the north-western edge of this area is a more-or-less square patch of shorter vegetationExternal link: it would require more than a superficial examination to determine whether this is of any significance, but it is just possible that it is a faint indication of the former presence of structures; at any rate, there are no foundations to be seen here.

NS4277 : Possible former site of a building by Lairich RigNS4277 : Possible former site of a building by Lairich RigA square patch of shorter vegetation.

The braided track itself makes an abrupt change of direction just to the south of the cultivated plot, which sits in the angle formed by the turn. There is nothing in the topography of this part of the moor to make such a change of direction necessary, and since the track would otherwise be expected to follow a more direct route, it seems likely that the track turns at this point simply because it had to go around the plot (and associated farm buildings, if there were indeed any here).

However, the track consists of several parallel hollow ways here, and the westernmost one slices throughExternal link the ridges and furrows at the south-eastern edge of the plot. One plausible explanation for this is that the track continued in use for a considerable time after the plot had been abandoned. The abandoned plot is tightly nestled within the angle formed by the track's abrupt turn; over time, with no remaining obstacle to following a slightly shorter and smoother route here, that angle would gradually be rounded off as people began to cut across it; parts of the track would thus begin to encroach on the abandoned plot.

I originally believed that this plot was associated with the vanished farmstead of Upper Garshake, and that the farm buildings themselves would once have stood beside it; Roy's Military Survey of Scotland shows that farmstead (as "Upper Garsheake") somewhere in this general area. However, a helpful contact at WoSAS brought to my attention the unnamed building marked at about NS42007675 on the first-edition OS map, and I am thoroughly convinced by his reasoning that this is a far more likely location for Upper GarshakeExternal link; furthermore, that location better corresponds to the position marked on Roy's map. As for the plot illustrated above, it is not clear which of the local farms it was associated with; my own opinion is that it is a relic of a much older farmstead, one that has not been recorded.

As for the track leading past the cultivated plot, it may well correspond to a route that appears on "A Map of the Shire of Dumbarton" (1777) by Charles Ross: that route is shown leading from "Mains" (of ColquhounExternal link) in Dumbarton, past "Waulkmiln" (the town's waulk mill), Crosslet and Greenhead, and then past Garshake, leading ultimately to "Whitehill" (present-day Meikle and Little White Hill). As my annotated satellite map shows, the main body of the braided track leads to areas of extensive but shallow quarrying on the western slopes of Meikle White HillExternal link; it is therefore a good candidate for being the route that is shown on the Charles Ross map. This also indicates that the track was, for at least a part of its history, employed in connection with the local limestone-burning industry, making it of relevance to the present article.

For the sake of completeness, my annotated satellite map also shows some much fainter tracks (of indeterminate age) that head west from the vicinity of the cultivated plot, and which lead towards Maryland and Priestyard, which are themselves of considerable antiquity.

After passing the ridged plot, the braided track continues to the NNE, fanning out considerably as it passes near the north-western edge of Black WoodExternal link, where a large number of parallel tracks can be seen (especially in the area around NS42627757). The area along the north-western margin of Black Wood was planted with treesExternal link in about 2014, and many of those tracks will therefore gradually disappear from view.

Shortly after passing the north-western tip of Black Wood, the braided trackExternal link passes the faint remains of another site of interest, a long-vanished farmstead, as described next.

A vanished farmstead north of Black Wood:

That farmstead is not shown on any map, but its remainsExternal link are clearly several centuries old (the farm and its enclosure are shown in an annotated satellite viewExternal link of their own). After finding the ruins of the farmhouse itself, I submitted a report to WoSASExternal link, who had no existing record of it.

NS4277 : Remains of an ancient farmhouse by Lairich RigNS4277 : Enclosure of ancient farmstead by Lairich Rig(left) The faint remains of a farmhouse.
(right) The north-eastern side of its associated enclosure.

The location of this farmstead is near the "H Killpatrick" (High Kilpatrick) that is marked on John Ainslie's 1821 map of the southern part of Scotland (I have not seen this name marked on any other map). However, that map is not sufficiently detailed to allow the farmstead to be identified with any confidence. In any case, given the poor condition of the remains, it seems unlikely that they are to be identified with a farm that was still in existence as recently as 1821. I consider the ruins to be much older.

I believe that this lost farmstead was also located, quite independently, by the Woodland Trust Scotland, while they were carrying out a survey of the area before planting trees. I later contacted them, out of concern that they might, with their new planting, inadvertently obliterate the relics of the farm building; to their credit, they were keen to ensure that the remains were preserved. A few years later, at around the same time that I was investigating the remains of the cultivated plot shown above, I revisited this area just north of Black Wood, and I can confirm that the area occupied by the ancient farmhouse was indeed left unplanted.

At the northern edge of Black Wood, one system of tracks heads eastwards, passing some limestone outcropsExternal link (NS43047764) on the way. Much of that area was planted with trees early in 2016. There are some quarry pitsExternal link and limestone outcropsExternal link near c.NS43387789, and the old braided track is particularly prominent where it passes over a large moundExternal link, caused by underlying limestone. Near there, the braided track crosses a very old boundary; the track cuts through the boundaryExternal link, providing visible evidence that the boundary is older than the track. The braids of the track cross the Roughting BurnExternal link at NS43737774 before fanning out and becoming rather indistinct. There are, though, signs of quarryingExternal link at their eastern end.

The main system of tracks heads, instead, in a north-easterly direction, to the western slopes of Meikle White HillExternal link. In this area, centred on NS43967851, there are signs of extensive surface quarryingExternal link on the slopes of the hill (particularly apparent in the 2005 satellite imagery).

As the annotated satellite map shows, another set of limestone industry tracks also lead to the western slopes of Meikle White Hill. These originate in the area around Spouts, and they will be discussed next.


Centred satellite map: LINKExternal link

Note that the remains in this area are represented in much greater detail in an annotated satellite viewExternal link of their own.

The farmstead of Spouts was located alongside a burn of the same name. The farmstead was already a ruin by the 1860s, when the first-edition OS map of this area was made; see CanmoreExternal link for further details. The farm building itself is now represented only by a few stones, but the rectangular enclosure that surrounded it is more easily visible, in the form of a low ridge.

(right) Traces of the large enclosure around the farm building.

Satellite imagery with favourable lighting reveals an abundance of old tracksExternal link leading away from the eastern (uphill) end (NS42837830) of the enclosure. The tracks begin very abruptly just outside the boundary of the enclosure, showing that the farmstead of Spouts was still in existence when these tracks were created. There are many limestone outcrops in this area, and signs that a great deal of surface quarrying has taken place here.

(right) One of the largest remaining outcrops to be found in the same area.

About 200 metres to the NNE of the old farmstead of Spouts is a site, located on the Spouts Burn, where there are a number of interesting survivals of the limestone industry (this was a new find).

The most visible feature here is a large green mound (NS42867849); this has a more or less circular depression in it, which is probably a decayed lime-kiln (it is rather similar to a nearby lime-kiln ruinExternal link in upper Auchenreoch Glen). In the area between the large green mound and a point 100 metres further downstream, various intriguing remains can be seen on both sides of the burn. These remains are in the form of small green mounds, differing from typical lime-kiln ruins in being much lower, and in lacking a central depression. The mounds occur in pairs, with each mound facing its opposite number directly across the burn. There are at least three pairs (in isolation, these small mounds would barely be noticeable, but their regular arrangement makes them a little more apparent). When I contacted WoSASExternal link to report the find, it was suggested to me, based on their appearance, that these small mounds were the ruins of simple clamp kilns (a more rudimentary form of lime-kiln); that identification does appear to fit these remains.

NS4278 : Possible lime-kiln ruin at the Spouts Burn by Lairich RigNS4278 : Mounds beside the Spouts Burn by Lairich Rig(left) Large mound; the hollow in it is probably a lime-kiln ruin.
(right) The smaller mounds in the foreground were probably clamp kilns. Like many of the other remains shown in this article, they are noticeably more green than their surroundings. This is because of a difference in vegetation cover caused by the presence of limestone (whether burnt or otherwise).

Although I have not made an explicit connection on the map, it is likely that this part of the network was joined to the other portions that lie just to the north-west. For example, an old boundary heads away in a north-westerly direction from this industrial site for a distance of about 200 metres, leading directly to the nearest lime-kiln ruin in Auchenreoch Glen.

Auchenreoch Muir

Centred satellite map: LINKExternal link

As mentioned above, in the section 'Maryland and BroadfieldExternal link', some tracks branch off from the Old Drymen Road at NS42707862. The road itself continues to the NNE. However, at about NS42907908, minor tracks branch off from it, and lead towards the ruins of a longhouse; that building is probably at least as old as the network of tracks.

NS4279 : Remains of a longhouse by Lairich RigNS4279 : Remains of a longhouse by Lairich RigRuins of a longhouse.

The Old Drymen Road, here deep and braided, continues to the north-east. However, a significant number of tracks branch off into an area where there are many signs of disturbance associated with former quarrying. The most noticeable features on the ground are: a large former quarry at NS42977936; a smaller former quarry at NS43007952; a line of test pits from NS42967968 to NS42977975; and a wall-like linear feature from NS42707969 to NS42817968. The longhouse, the quarries, the test pits, and the other features in this area had already been reported; for details, I refer readers to a report at WoSASExternal link, where the remains are very well described and interpreted (on a personal note, I should add that I had taken the round pits to be lines of bomb craters, of which there are several elsewhere on the moor). Some of these features are shown below:

(right) One of a line of old test pits.
NS4279 : Old test pit by Lairich RigNS4279 : Old spoil mound by Lairich Rig(left) Another test pit in the same line.
(right) This was probably a spoil mound.

One of the goals of the present article is to allow these remains to be seen in a new context, as part of a much larger network.

The Old Drymen Road (below, left) continues in the direction of a long natural ridge called the Lang DykeExternal link. On the way, it passes a large cornstone outcrop (below, right); there are some signs of disturbance in that area.

(right) A large cornstone outcrop; incidentally, this is the same outcrop as is pictured in Plate 1b of [Mitchell1995].

Just beyond the Lang Dyke is one of the most important parts of this network; that part will be described next.

Near the Lang Dyke

Centred satellite map: LINKExternal link

The area just to the north of the Lang Dyke contains numerous remains associated with the limestone-burning industry. These have been known for some time; for example, I.M.M.MacPhail, writing in the booklet "Off the Main Road" (1979) notes that "just to the north of a ridge called the Lang Dyke, which is a geological, not a man-made dyke, may be seen the site of old lime-kilns, marked by bright green knolls". Likewise, in [Mitchell1995], this area is listed as "site 5, Merkins Muir", with "kilns present".

Given that this area is one of the most important parts of the network, the remains to be seen here are worth describing in some detail.

First of all, there is a large area where surface quarrying has taken place; the area is centred on NS43888067, and is still conspicuous for its undulating and bright green appearance. About 350 metres to the NNE (NS44038098) is a deeper, crescent-shaped quarry pit. 120 metres to the north-east of the area of surface quarrying is a much deeper quarry pit (NS43968075), which is now partly water-filled.

NS4380 : Former limestone quarry by Lairich RigNS4380 : Pool (in a former limestone quarry) by Lairich RigTwo views of a former quarry pit, now partly water-filled.

Just to the north of that pit are the remains of a large lime-kiln (NS43978077). This is very different from the ruined lime-kilns that are found in Auchenreoch Glen and the Murroch Glen; the ruined kilns in the glens appear as circular mounds, about 3 metres across, with a central depression. Instead, this ruined lime-kiln is rectangular in shape, and set into a north-facing slope. It is 10 metres wide (E-W), and extends back into the slope for a distance of 4 metres (N-S). This is certainly the largest of the lime-kiln remains on the network, and it was undoubtedly also the most important of the kilns. It also lies near the intersection of the two old roads (shown as blue lines on the map: the Old Drymen Road running SSW-NNE, and the Common Drove Road running W-E). The kiln was therefore very well placed for access.

Further signs of disturbance, in the form of a pit that is open on one side, can be seen not far to the west. It is the remains of a kiln (lower-right image, below).

Note that [Mitchell2013] contains a photograph of this kiln, with the bracken cleared, and a useful description of it.

The Old Drymen Road, shown in blue on the map, now heads off to the north-east, as will be discussed in a later section (the-north-eastExternal link).

However, another route, shown in red on the satellite map, branches off northwards from it, passing just to the east of these industrial sites, and heading towards Red Brae, which is discussed next. Some subsidiary tracks also branch off towards the large kiln shown above, and towards the various nearby quarries.

Red Brae

Centred satellite map: LINKExternal link

The main track now passes through an area that is labelled Red Brae on the map (the name is an old one, and is mentioned, along with several other names that survive in the area, in a 1609 charterExternal link by James VI). Cultivation traces are visible on the slopes just to the east of the burn, and an unfinished millstone can also be seen there (see CanmoreExternal link for details):

(right) A third area, furrowed ESE-WNW; it appears on the right in the distant view, and it also contains the unfinished millstone shown above.

The cultivation traces are much more extensiveExternal link than they first appear: they extend for hundreds of metres E-W and N-S, but, for the most part, they are no longer very visible. The millstone had already been reported, as noted above; as far as I know, the cultivation traces had not. In addition, I came across the remains of an enclosure here (also previously unreported). The track to Red Brae skirts that enclosure's western side. The cultivation traces and the enclosure provide strong evidence that there was once a farmstead located here.

NS4481 : Remains of an enclosure by Lairich RigNS4481 : Remains of an enclosure by Lairich Rig(left) The enclosure, seen from its northern end.
(right) A view from the other end.

A track continues NNE in roughly the direction of Merkins Farm, but I did not follow it further in that direction, nor have I included it on the satellite map; it is a genuinely ancient track, shown on the old Plan, but much of its present-day appearance will have been the result of recent traffic from Merkins Farm.

(There appear to be other tracks leading away from Red Brae: they head ENE, along the northern bank of the Finland Burn; they cross the Gallangad Burn at about NS45098181, and then head north-east to about NS45248206 (on Gallangad Muir), where there is a bendExternal link in an old field dyke associated with the remains of a farmsteadExternal link. The farmstead is marked, but not named, on Roy's Military Survey (1740s-50s), and it may have been abandoned even at that early date. Just 30 metres to the SSE of the bend in the field dyke, there is an old quarry pitExternal link. On the map, I have added these remains to the network, but using only a faint red line, since it is not clear whether the connection between Red Brae and that area is an ancient one or not.)

At about NS44328817, a track branches away from Red Brae, and heads westwards to Blairquhomrie Muir, where a number of remains can be seen. That area will be discussed next.

Blairquhomrie Muir

Centred satellite map: LINKExternal link

From Red Brae, a branch of the network leads for almost 2 kilometres to Blairquhomrie Muir. In this outlying north-western part of the network, there are two lime-kilns, some limestone outcrops to provide raw material, and signs of surface quarrying nearby:

(right) Some limestone outcrops (NS42678153) beside a burn.

There is one more part of the network to be discussed: from just south of Red Brae, the Old Drymen Road continues towards the north-east, as discussed next.

The north-east

Centred satellite map: LINKExternal link

The track is shown in blue on the satellite map to indicate that it is one of the two old roads that are depicted on the early-nineteenth-century "Plan of Dumbarton Muir". There do not appear to be sites alongside it that are particularly related to the limestone industry, but there are other features of interest nearby.

Beside the point where this track heads away from the one leading to Red Brae are what may be the faint traces of a pair of rectangular structures (previously unreported, and shown below); on the ground, the evidence for this pair of possible structures is not very obvious, but it finds support in the 2005 satellite imagery. The course of the old road that leads away from there is still visible in a few places:

NS4480 : Possible remains of a structure by Lairich RigNS4480 : Traces of an old road by Lairich Rig(left) This is possibly the corner of an old structure.

NS4480 : Traces of an old road by Lairich RigNS4481 : Traces of an old road by Lairich Rig(left) Further along the old road.
(right) It runs alongside an old boundary here.

For several hundred metres, the road runs alongside a faint old boundary (also unreported), which is visible in the form of a low ridge:

NS4481 : Remains of a boundary by Lairich RigNS4481 : Remains of a boundary by Lairich Rig(left) The boundary's western end; the road is on the right.
(right) A view along the ridge.

(right) The boundary fades away not far beyond this point.

Not far to the south-east of the ridge was a circular water-filled pit, perhaps an old quarry pit. A little further to the south, an almost rectangular area was outlined by a ditch; within it were what appear to be the faint traces of some small rectangular structures (unreported). They are of uncertain date, but, in shape and size, they are not unlike those mentioned at the start of this section.

(right) Green ridges indicate the end-walls of some small rectangular structures.

The Old Drymen Road continues ENE, but fades out before it reaches the Gallangad Burn; I have represented its presumed continuation by means of a fainter line on the satellite map. Traces of the road can be seen where it crosses the Gallangad Burn, and it becomes clearly visible once again on the far side of the burn:

NS4581 : Remains of a road by Lairich RigNS4581 : Remains of a road by Lairich Rig(left) The approach to the Gallangad Burn; it is more clearly visible on satellite imagery.
(right) The road is clearly visible as a hollow way on the far side of the burn.

(As for the other old road, the Common Drove Road, that is shown on the Plan, it is described below, in the section 'Other sites of interestExternal link'.)

This concludes the discussion of the main network of tracks. As was noted above, this network is primarily related to the quarrying and processing of limestone, in the form of cornstone outcrops that are found scattered over the moor. However, there was another important raw material; that subject will be discussed below in the section headed 'the glensExternal link'.

Before that, however, it would be useful to discuss some issues related to earlier reports about the moor.

Problematic reports

An elusive road

The Canmore archaeology database contains several entries corresponding to a series of reports made in the 1970s, and initially appearing in the journal DES (Discovery and Excavation in Scotland). The reports refer to a road crossing these moors: report 1External link / report 2External link / report 3External link. They also allude, in passing, to the limestone tracks, calling them "mineral tracks". The road, as described in reports 1 and 2, generally passes a considerable distance to the east of the network that is described in the present article. However, with the exception of a very indistinct moundExternal link near Milton, I have been unable to locate any trace whatsoever of the supposed routes described in Canmore reports 1 and 2.

In contrast, the hollow way described in report 3 does correspond to a visible road, namely, the one that I have been describing; more specifically, it describes it near the point where it crosses the Gallangad Burn.

I began to suspect that what was being described in Canmore report 3 was not, in fact, connected with what (if anything) was being described in reports 1 and 2, but was, instead, the continuation of the old road that I have been describing in this section, a road which has its beginnings near Maryland Farm. The "Plan of Dumbarton Muir" confirmed that my suspicions were correct; it shows this route, which it labels "Road to Drymen &c", crossing the Gallangad Burn near the Lang CairnExternal link and then heading roughly north-east. See the referencesExternal link, where the course of this Old Drymen Road, as shown on the Plan, is described in more detail.

In any case, the road that I am describing is most certainly not a continuation of the supposed Roman causeway (see the next subsection) at Milton that is described in report 1.

As for Canmore reports 1 and 2, which describe a route of which I could detect not the slightest trace on the ground, the following explanation occurred to me: unlikely though it may seem, the authors of those reports appear to have been describing a route that I have mentioned many times in the present article: the old road to Drymen. However, I believe that they mistook Square Wood for Black Wood, and that this led, in turn, to a whole series of similar misidentifications, with the result that the entire reported course of the road was displaced by a very considerable amount.

In detail, the displacements appear to be as follows:

(1) Report 2 says that the road can be followed "from the NE end of Black Wood", while the road I am describing passes the NE corner of Square Wood.

(2) The report goes on to mention "one small pillar mile marker, inscribed 3, still in position", supposedly in the vicinity of Meikle White Hill. This is surely the old cattle stance markerExternal link, with the figure 3 inscribed on top, that stands on the Lang Dyke; it is a long way from Meikle White Hill, but is close to the road that I have been describing.

(3) Finally, the report mentions lime-kilns near "the Black Burn Ford", with a link to a related report (report 4External link), which provides further details. Though these remains are supposedly to be seen beside the Black Burn, the descriptions correspond to the appearance of prominent lime-kiln ruins that can be seen to the north of the Lang Dyke, close to the Finland Burn, which was presumably mistaken for the Black Burn. According to report 4, the remains include a "rectangular enclosure" (almost certainly the large rectangular kilnExternal link near the Lang Dyke), and a "single kiln" (presumably the smaller lime-kiln ruinExternal link that, in reality, stands on the bank of the Finland Burn). It is worth adding that I have, on more than one occasion, searched the area beside the Black Burn, as specified in report 4, and saw no such remains there. Furthermore, report 4 mentions "mole hills" in the area: the ground beside the Black Burn is very boggy, and no molehills would be found there; in contrast, the lime-kilns that are beside the Finland Burn are in a grassy area.

My proposed explanation may seem highly speculative, but not only does it account for the fact that I could find no trace whatsoever of the purported road described in reports 1 and 2, but it also explains why the features reported as being alongside that road seem suspiciously like displaced versions of what can be found alongside the old road to Drymen. See the section 'othersExternal link', below, for what appears to be another example of a displaced report from around the same time.

I have discussed this subject here at considerable length since it may help anyone who is puzzled, as I was, by these Canmore reports (dating from the 1970s), which do not appear to correspond to any visible remains. In fairness to the authors of those reports, I should point out that they did not have the benefits of modern GPS technology, and were probably unfamiliar with this area.

Although it is not directly relevant to the present article, it is perhaps worth my making some observations about other reports made at the same time. That is the topic of the next two subsections.

A supposed causeway

Another reportExternal link, from about the same time, mentions remains, described as those of "a causeway"*, on the southern shore of the River Clyde near Bishopton. This interpretation has found its way onto the map: the linear feature on the southern shore is currently labelled "Remains of Old Causeway" on large-scale OS mapping. However, I believe that this supposed causeway is nothing more than the remains of a jetty; I discuss this subject at lengthExternal link elsewhere, and so do not need to repeat the details here.

(*) Report 2, mentioned in the previous subsection of this article, ends with the comment "for other stretches of this road, see ..."; the report thereby attempts to connect the elusive road with the supposed causeway on the south shore of the Clyde and a very indistinct moundExternal link on the northern shore, near Milton Island (see report 1External link). A further report (published in DES, 1980, page 35) on this topic is terse: "NS 423743 - NS 439782 The road has been traced from the Clyde to Little White Hill. Details from reporters." This appears to be an attempt to link the causeway with the road that report 2External link describes as passing Little White Hill; however, this is problematic: as discussed in the previous subsection of the present article, the actual road does not pass anywhere near that hill.


Another reportExternal link from about the same time describes the following feature, which is supposedly at NS452799External link: "On the E bank of Knockupple Burn beneath the rocky crag, a rectangular steading with a small oval store shed to E".

I have been unable to locate any such structure in that area. I may simply have missed it, but it seems to me that the report is a fair description of the remains of a structureExternal link that can been seen about half a mile to the NNE of there, at the foot of a crag. I suspect that the report is a displaced duplicate of another oneExternal link, which gives the correct position of the ruin that it describes. The first-edition OS map identifies this structure as an "old sheep ree"; in the present-day ruins, which are in poor condition, it can be seen that the eastern corner had been walled off at some point, perhaps to form a lambing pen.

The glens

In parallel with the quarrying and burning of cornstone, discussed above, another form of limestone was being found and processed in this area: this was cementstone, an impure form of limestone that occurs as layers of nodules in the deeper, steep-sided parts of the Murroch Glen and Auchenreoch Glen, and in a few other places (as illustrated below).

NS4178 : Auchenreoch Glen by Lairich RigNS4378 : Cementstone nodules in the Spouts Burn by Lairich Rig(left) Lower Auchenreoch Glen, with crumbly slopes on either side.
(right) Cementstone nodules, of the kind that can be found in abundance in these glens; the ones shown here are in the Spouts Burn.

The cementstone was burned in kilns that were located deep down in the glens, close to the stream-bed. The rocks to be burned, and the water to slake them afterwards, were therefore close at hand; however, people still had to get to and from the kiln, fuel had to be brought in, and slaked lime had to be taken out. The steep sides of these glens could make access difficult. One practical solution was to make use of some long ridgesExternal link that extend down into the Auchenreoch and Murroch Glens. The location of these long ridges would have been a major factor in determining where to construct the kilns. For example, the images below show a long ridge that leads into the lower Auchenreoch Glen, and a ruined kiln that can be reached by means of that ridge:

NS4178 : Ridge leading into Auchenreoch Glen by Lairich RigNS4178 : Lime-kiln ruin in lower Auchenreoch Glen by Lairich Rig(left) A ridge leading into lower Auchenreoch Glen.
(right) A lime-kiln ruin, set deep within the same glen.

Although these ridges do make access a little easier, they are very narrow, with steep slopes on either side. Particularly in bad weather, negotiating these ridges with a load of fuel, or of lime, would have required a great deal of care. The kilns themselves had to be kept burning for several days and nights on end a demanding task.

(The fact that lime-kilns were located in remote places is something for which the residents of nearby Dumbarton would have been grateful; the kilns would have emitted a great deal of smoke, and an unpleasant smell. Also, slaking the burnt stones was a noisy process: as David Ure, writing in the 1790s, put it, in the language of his day, it resulted in "very loud explosionsExternal link".)

The lime-kilns in these glens were all built to the same plan: their ruins are invariably in the form of a circular turf-covered mound, about three metres in diameter, with a central depression. A few representative examples are shown below (for more of them, see an indexExternal link to the kilns in the Murroch Glen). Though they may appear to be in a poor state of preservation, it is likely that the kilns are substantially intact beneath the turf: the final picture in the set shows an exposed section of wall, and provides evidence that these kilns were built with considerable skill:

(right) A different kiln in the same glen.

(right) Another kiln; a skilfully-built section of the original wall is exposed to view.

Perhaps because of their unique situation, and the fact that the needed limestone and water were at hand, the kilns in the glens do not appear to have been closely linked into the wider network of tracks that was described above. Nevertheless, they represent another aspect of the same industry; accordingly, I have included these kilns on my map of the network.


Dumbarton Muir:
Much of the area that is discussed in the present article is covered by one of the British Geological Survey's 1:50000 maps, namely, "Glasgow" (Scotland Sheet 30E, Solid Edition). Those parts of Dumbarton Muir where cornstone outcrops are evident are marked KNW on the map, for Kinnesswood FormationExternal link. Auchenreoch Muir is marked BGN for Ballagan FormationExternal link. Blairquhomrie Muir, to the north-west, is marked SCK for Stockiemuir Sandstone FormationExternal link. Further information about those formations can be found at the corresponding links (which are to the BGS Lexicon).

Carman Muir:
It would be very time-consuming to explore all of Dumbarton Muir. However, cornstone beds can also be seen on Carman Muir, a much smaller area that is only a few miles from Dumbarton Muir. There, sandstone (Stockiemuir Sandstone Formation) is prominent to the north side of Cardross Road, while the area to the south of the road is characterised by cornstone beds (of the Kinnesswood Formation), which there overlie the sandstone. The area is covered by the BGS 1:50000 map "Greenock" (Scotland Sheet 30W, Solid Edition).

Mainly to satisfy my own curiosity, I carried out a very informal survey of Carman Muir, recording the position and alignment of the main cornstone deposits, and the locations of prominent outcrops and quarry pits, as well as smaller circular hollows that may once have been test pits. The findings are recorded on their own annotated satellite viewExternal link, on which the markers provide links to corresponding pictures and descriptions on Geograph; there is also a shared descriptionExternal link for those pictures; it provides a brief summary of the geology of the area.

There are signs of quarrying on various scales across Carman Muir, but the focus of the lime-burning industry in that area appears to have been a knollExternal link, where the visible traces include extensive spoil moundsExternal link and the remains of a lime-kilnExternal link.

Other sites of interest

The region covered by the network of tracks on Dumbarton Muir includes a number of other interesting archaeological sites that are not directly connected to the limestone industry. Several of these, such as the vanished farmsteads, have already been discussed in their appropriate places. The present section discusses a few of the other archaeological sites of interest that can be found in this area.

One of these is the Common Kist: this is a cist burial (effectively an ancient coffin with stone slabs forming its sides); it is named from its location on Dumbarton Common Muir. A 1609 charter by James VIExternal link mentions a number of places that lay on the moor's boundary (the reported wording of the charter varies from author to author, but the differences are generally minor, and of little importance); among them was the "auld monument of stane callit the Common Kist". The cist would, at one time, have been covered by a large cairn of stones. These stones were removed centuries ago, and were probably used to make the dry-stone walling that can be seen nearby. At a later time, the cist itself was damaged by local landowners: writing in 1896, author John Guthrie Smith describesExternal link how these local lairds separated their respective lands by means of a wire fence, and "they or their servants committed the gross piece of sacrilege of placing in the very centre of the 'Common Kist' a large straining post, and fastening it in its place by breaking up one of the sides and the foot of this most interesting monument of the past for packing to keep in its place their truly 'infernal machine'!" (incidentally, the Common Kist fell within the boundaries of the proposed wind farm mentioned at the start of this article).

A similar cist on Auchenreoch Muir was found by a walker (see WoSASExternal link for details) in the 1990s. Both cists are illustrated below:

(right) A closer view of the chamber.

Another interesting site is the Hill of Standing Stones, the centre of the proposed windfarm:

NS4380 : Hill of Standing Stones by Lairich RigNS4380 : Summit of the Hill of Standing Stones by Lairich Rig(left) The Hill of Standing Stones: the summit cairn.
(right) The summit in winter.

This location was also mentioned in the 1609 charter; in connection with the boundaries of the Common Muir, the charter speaks of "the north-west part of the hill where the Standand Stanes are fixt". The received wisdom is that the hill was named either after the cairn that once covered the nearby Common Kist, or after the large "cairn" (really just exposed bedrock) that underlies the more modern marker cairn on the hilltop. The wording of the charter does not really lend support to either interpretation; yet, when the Ordnance Survey's Object Name Books were compiled in the 1890s, it was recorded that there were, at that time, no standing stones on the hill; nor was it believed that there ever had been any.

My own belief (which at least fits all of the above circumstances) is that the "standing stones" of the hill's name were march stones, boundary markers. As for what has happened to these stones, I believe that they may have been incorporated into the summit cairn, which contains a number of stone posts, some with distinctive markingsExternal link.

Some time after I had written the first version of this article, transcriptions of the earlier (c.1860) OS Name Books became available online. Their entry for the Hill of Standing Stones appears to support my theory about the hill's name: "Hill of Standing Stones A small eminence on the summit of which are many large loose Stones marking the Boundary point". In all likelihood, the "large loose stones" that are described there as marking the boundary point are the very same ones as those that now make up the cairn on the hilltop.

As was pointed out earlier, in the section 'Maryland and BroadfieldExternal link', the backbone of the network of limestone industry tracks (i.e., the track beginning at Maryland Farm) was an old road to Drymen; it has also been described as a drove road. However, there was another important drove road passing from west to east through the area of interest; the route of this old drove roadExternal link is depicted as a blue line on my map. It began at Bonhill, at about NS39867960, where there is now a disused quarryExternal link; it then headed up over Pappert HillExternal link (NS4280), and then led east over the Hill of Standing Stones and the Lang DykeExternal link, crossing the Gallangad Burn at the Common FordExternal link. The course of the drove road fades out between the Lang Dyke and the point where it becomes faintly evident again near the Common Ford; between those points, I have represented its presumed course by means of a much fainter line on my satellite map.

See [Rankin] in the referencesExternal link for more on the Common Drove Road.

Appropriately, one of the stones in the summit cairn of the Hill of Standing Stones is an artefact related to droving, namely, a cattle stance markerExternal link (with the digit "1" carved on its top), which marked the site of a stance, a point where drovers and their herds might stop for the night. Another cattle stance markerExternal link, numbered "3", stands 880 metres further to the east, on the long ridge known as the Lang Dyke. Marker number 2 lay between them, but it was removed to Merkins Farm many years ago.

The Hill of Standing Stones may not have any standing stones in the usual sense, but it is not without archaeological interest; what may be two ancient cairns are located near its summit (see CanmoreExternal link for details):

NS4380 : Remains of a cairn on the Hill of Standing Stones by Lairich RigNS4380 : Possible cairn on the Hill of Standing Stones by Lairich Rig(left) A possible ancient cairn (NS43658045) on the Hill of Standing Stones.
(right) Another possible ancient cairn (NS43668046) on the same hill.

Did this drove road over Pappert Hill and the Hill of Standing Stones also serve the limestone industry? Very probably: a quarry pit with an exposed rock face (below, left) can be seen just to the east of the point where the drove road emerges from Nobleston Wood onto the muir; further signs of quarrying (below, right) can be seen just to the north-east of the summit of the Hill of Standing Stones:

(right) A rectangular area of quarrying near the Hill of Standing Stones.

If this drove road also served the limestone industry, as is likely, then it becomes clear how these two otherwise isolated sites are to be linked into the network of tracks. In addition, this route would allow easy access from Bonhill to the very important complex of sitesExternal link located to the north of the Lang Dyke, including what was probably the main kiln, as well as several very large quarry pits.
