Stob Bàn exhibits striking examples of Dalradian rock geology and has been identified by the Joint Nature Conservation Committee (JNCC) as an important site in its Geological Conservation Review. Dalradian rocks were characteristically formed in the high ground to the east and south of the Great Glen of Scotland. Dalriada was the name for this ancient Celtic region. The mountain should not confused with another Stob Bàn, also a Munro which is located in the Grey Corries above Spean Bridge.
