... presented a general stratigraphy for the same area based on sections in north-west Lewis and at Port of Ness, which essentially comprised a tripartite succession of two till units with interbedded layers of stratified sand, gravel and clay. At Port of Ness the lower till contained shells and lenses of sand incorporated from the sea floor. The stratified sediments above consisted of coarse gravel with shell fragments. The upper till, which also contained shell fragments, was capped by a further layer of stratified gravels and sands. (...) At one locality, a hollow in the underlying bedrock showed a layer of till interbedded with sands and gravel.
