The site is marked, as Chappeltouns, on the Blaeu Map of the Lennox (published in 1654, but based on earlier surveys), and as Marrockhill on Ainslie's 1821 "Map of the Southern Part of Scotland". The relevant OS Name Book, compiled in 1860, observes that the name Mattockhill was the one given by the tenant, by the factor, and in the Valuation Rolls; it records the alternative names High Chapelton, from an estate plan, and Chapelton, from a county map, but observes that those names were no longer in use. The Farm Horse Tax Rolls for 1797–98 have an entry for "Robert Paul, Chappel". That this is the same place is made clear by John Bruce's 1893 book "History of the Parish of West or Old Kilpatrick", which states that Robert Paul was the tenant farmer of Mattockhill in 1796, and that he was one of five local men who were chosen, on the 17th of July of that year, to serve as church elders for West Kilpatrick Parish.

The site is no longer an oil terminal, and its structures have been cleared away; however, as of early 2018, the site is still closed to the public. See Link (at Canmore) for further details.

The information in the next paragraph was obtained from the booklet "Dunbartonshire: The Official Handbook of the County" (1965); note that, in this context, "bunkering" is the act of refuelling a ship, and "bunker(s)" is the fuel oil itself:

The terminal was operated by the Esso Petroleum Company, and was its main storage and distribution point in Scotland. The site was originally developed as a marine bunkering point after the First World War, but was later extended to 150 acres, and expanded to make it a major ocean terminal capable of handing a wide range of oil products. The terminal was mainly supplied from Esso's refineries at Fawley (SU4403) and Milford Haven (SM8706, now the site of South Hook LNG Terminal) by ocean tankers which could be accommodated at either of the Bowling jetties. The largest tanks around the jetties were capable of storing 8000 tons of oil each. In the mid-1960s, when the aforementioned booklet was written, bunkering was still a feature of the site: deliveries to ships in Glasgow docks were carried out by self-propelled bunkering barge, while bunkers could also be pumped aboard directly from the terminal at the coaster berth.

Associated with the former terminal is a group of standing structures in the Clyde; they are identified as "bollards" on OS mapping.
