ABBEY CRAIG

The 'Abbey Craig' is the hill upon which the Wallace Monument stands, at Causewayhead, just to the north of Stirling, Scotland.
The Abbey Craig is part of a complex quartz-dolerite intrusion or sill within carboniferous strata, at the western edge of the Central Coal Field, known as the Stirling Sill. The quartz-dolerite, being much harder than the surrounding coal measures, has been exposed due to erosion, including by glaciation. The characteristic crag and tail shape of the crag reflects this glacial shaping.
''Craig'', or ''crag'', describes a post-glacial Crag and tail landscape feature. The abbey is Cambuskenneth Abbey, on the north bank of the River Forth, about 1 km to the south.
