A study of certain small‐scale fluted moraines, all less than 4m high but up to 400m long, in the Torridon area has shown that they are subglacial features composed of a clast‐rich till, and formed in the Loch Lomond Stadial beneath ice with a maximum depth of 100‐200m. The evidence from lithological analysis of till samples from the fluted moraines suggests that they were formed by subglacial deformation of a pre‐existing till with little in the way of net down‐glacier movement of the material.
