Glen Valtos in the north of the Isle of Lewis is the remains of an ice-age glacial overflow channel. DETAILS IN DESCRIPTION.
Glen Valtos was formed by the decay of the Late Devensian ice-sheet approximately 18,000 - 14,000 years ago. It is the remains of a glacial overflow channel carved beneath ice as the meltwater flowed away to the east (in direction of photograph). At one point a lake of meltwater formed to the west where it was dammed by an ice mass in Camas Uig and it is this lake which is thought to have drained away and carved this channel in the process. The valley is now a Site of Special Scientific Interest and contains the B8011 road, the only land connection between Uig and the rest of Lewis.
