Description: The landscape is typical of the north-western Highlands. A very ancient Lewisian gneiss basement (granulite facies gneiss, c. 2700 Ma. old) formed a rocky undulating land surface onto which there was a great deposition of Torridonian sandstones and grits in a semi-arid environment at c. 1000-800 Ma. After a very long period of erosion and glaciation, this essentially stable foreland consists of massive isolated mountains called inselbergs separated by wide expanses of lower-lying undulating areas. A fine panorama of most of the mountains of the Assynt district which are relicts of reddish-brown Torridonian sandstone and conglomerate resting unconformably on an irregular basement of Lewisian gneiss. View northwards.
