Cass
The topography of the Cass area was formed by repeated glaciation in the Pleistocene, with the valley floor built up by river fans as the glaciers retreated and the nearby Lakes Sarah and Grasmere enclosed by moraines and ice-eroded rocks. Many of the valleys around Cass post-date the retreat of the Poulter Glacier 13,000 years ago, and are caused by erosion.
