As seen in satellite imagery, the pattern of ditches shown here is a very prominent feature: Link
A pool (NS3678 : A pool on Carman Muir
) is visible as a dark shape in the left of that satellite image; directly to the right of the pool, in the right-hand side of the image, is a prominent three-fold meeting point, where areas of ditches oriented in three different directions meet; the area around that meeting point is the one shown in my photograph, but it is just a small portion of a much larger area of land covered by this pattern of lines. The photograph was taken from a small rock outcrop on an area of slightly higher ground to the south-west.
Former use of the land here has clearly left its mark. An article by the naturalist John Mitchell was recently brought to my attention (see NS3678 : Former cornstone workings on Carman Muir
); concerning this area, it says: "site partially drained for forestry in 1986, but planting not carried out". This may explain the many prominent channels visible here and nearby.
[Trees had also covered this area at an earlier period; they are shown on the first-edition OS map (c.1860), but had been cleared by the time of the second-edition map (c.1898).]
While photographing the area, I measured (using GPS waypoints) the spacing of the ditches, and found them to be set 5 or 6 metres apart.
On the skyline, the television transmitter (NS3779 : Millburn TV Mast
) on Millburn Muir is visible near the left-hand edge of the photograph; to its right, above a closely-spaced pair of poles, NS4385 : The Dumpling
is visible as as a bright bump set against darker distant hills. Also on the skyline, at the right-hand edge of the image, the wooded area (NS4280 : Moorland near the summit of Pappert Hill
) around the summit of Pappert Hill is visible; to its left is Auchincarroch Hill (near which a landfill site is located: NS4181 : Road to Auchencarroch Landfill Site
