The more broken southern side is dominated, at least in its upper reaches, by three (Corbetts; the 835m high Sgurr Cos na Breachd-laoidh, the 858m Fraoch Bheinn and the 880m Sgurr Mhurlagain.
[1] The glen runs through territory formed by psammites and pelites of the late Precambrian Glenfinnan Group of the Loch Ness Supergroup, a thick sequence of metamorphosed rocks which is intruded by the West Highland Granite Gneiss in the middle section of the glen.
Much of the lower part of the glen is planted up as a commercial forestry plantation, contiguous with plantations in Glen Garry.
