A REMARKABLE GLACIAL PAVEMENT
Jack Saxon

I recently took a walk along the forest road near Brabster which runs south of Loch Sourach and branches off round Loch Thormaid. Just before the road petered out there was a forestry sign which read Achvarasdal. Some hundred meters further on the road lies a bedding plane of Old Red Sandstone on which there were literally hundreds of parallel striae a centimetre or so apart. I was intrigued enough to take my compass to determine the direction of the striae. The bearing was 320deg.  or 40 degrees west of magnetic north. This is roughly in keeping with the general trend of the ice movement over Caithness.
