Inchnadamph Bone Caves

The cave entrances, at the top of the green slope, are in shadow most of the day. They must have been formed by the action of water, but erosion has cut the glen down through them, leaving them high and dry. On the other side of Creag nan Uamh ('Crag of the Caves') cavers have recently found an excavated a shaft leading down into a large cave system, including a chamber of impressive dimensions. The longest cave system in Scotland is accessed from Uamh an Claonite nearby.

Red Rocks near to Brae of Achnahaird

The red is staining from the overlying sandstones, while the shape of the inlet is the result of erosion on softer mudstones and limestones overlying ancient gneiss.

Microbial Limestone

This red laminated rock is microbial algal limestone, which represents the oldest life form in Britain and Ireland. It was produced by microbes which grew in mats over the rock, fixing limestone and then growing over the earlier layers. The red colour is caused by staining from the overlying sandstones.
