Ben Vane is a Scottish mountain situated in the southern Highlands. The underlying geology almost entirely comprises the Beinn Bheula Schist Formation - Psammite and Pelite with a Siluro-Devonian Dyke prominent round the northern and eastern face. It is one of the Arrochar Alps and stands slightly separate from the other mountains of the group being connected on its western side to the neighbouring Beinn Ìme by a low col at 492 metres. Ben Vane itself just qualifies as a Munro reaching a height of 915 metres and is characterised by steep and rugged slopes which fall away to the Inveruglas Water to the east and the Allt Coiregroigan to the south; to the north the descent is more undulating going over the subsidiary top of Beinn Dubh before falling to the valley at the north end of Loch Sloy. Dense forestry cloak the mountain on its lower southern slope in Allt Coiregroigan. Also on these southern slopes by the Allt Coiregroigan is a disused quarry which provided crushed stone used for the construction of the Loch Sloy dam in the late 1940s. The dam wall lies two km to the north of the quarry and a conveyor belt was constructed to carry the crushed stone over the lower slopes of Ben Vane to the batching plant beside the dam.
