It takes its name from OS Pathf. Coalpit Den, which is the north-west part of Rameldry Den. The now ruined but still impressive settlement of Coalpitden is shown but not named on SGF. OS Pathf. marks a disused shaft nearby, and there are traces of spoil-heaps round about. For more on coal-mining in this area, see KTT Introduction, Coal, and Coaltown of Burnturk KTT, next head-name.
Both the 1753 and 1767 forms lack the final t of pit. This is most likely due to the fact that in the doubling of dental stops (t-d), the first one is absorbed into the second one.
