Development of potholes in Monessie Gorge, Grampian Region

The upstream end of Monessie Gorge. Grampian Region. Development of potholes in the Leven Schists Formation, Appin Group, Dalradian Supergroup. The gorge is cut into garnetiferous quartz-mica-schists of the Leven Schist Formation with a dominant spaced cleavage. The impressive potholes are due to abrasion rounded, massive quartzite and granodiorite boulders swept downstream from Inverlair and from the Strath Ossian Igneous Complex respectively.
