Stob Ban & Mullach nan Coirean
There are many boulders of schist, and some of quartzite, by the path. The bedrock here, however is Mullach nan Coirean granite the same rock as in the Lower Falls. There are also glimpses of red granite slabs in the Allt Coire an Mhusgain some distance below the path. Looking back there are fine views of the Polldubh Crags with Càrn Dearg South-West, an outlying top of Ben Nevis, behind.
