"The Bone Caves are a series of natural caves set into a high limestone cliff called Creag nan Uamh (Crag of the Caves). The caves are named for the large numbers of animal bones found during excavations.
There are four main cave openings in the cliffs, formed before the last ice age by water dissolving limestone in cracks in the surrounding rock. Subsequent glacial action and erosion of the glen by water left the caves hundreds of feet above the valley floor." PiP.
