Stanage End boundary stone

A boundary stone at Stanage End, the northern extremity of Stanage Edge. There is also quarry debris here.

Stanage Edge is comprised of Rivelin Grit (aka Chatsworth Grit), Namurian age, Upper Carboniferous. The coarse-grained gritstone was deposited in a series of delta distributary channels. The gritstone is normally strongly cross-bedded.

The illuminated face of the boundary stone has the letters 'WM' carved in it, presumably the landowner at the time (early 20th century?). If anyone knows the identity of WM, please post a comment below.

The opposite face to the WM has the letters 'WW' carved in a similar fashion, and this presumably relates to the landowner William Wilson who owned much of the Hallam Moors to the east in the early 20th century and who was also responsible for the carving of the grouse drinking basins shown in earlier photos posted here.
