At Scarisdale , on the side of Loch na Keal, are found the best example of P-forms in the whole of the UK. P-forms are a glacial feature where the bedrock is gouged by a combinations of glacial erosion and meltwater. The result is deep grooves and channels in the rock oriented with the direction of flow of the glaciers.
The P-forms at Scarisdale are right at the edge of the road and are very easy to find.

P-forms are also seen further back along the road towards Knock, esp at the tidal island of Eilean Feoir. They can also be seen in a few places above the road, but the best locality is at Scarisdale.

In addition to the glacial P-forms which are a recent feature, there are also some good examples of dykes of the Mull Swarm in this area, one of which can be seen following a sinuous track across the rock where the P-forms are found. Dykes are profuse in the Loch na Keal area.
