    View E from Cwm Idwal (near outlet stream of Llyn Idwal). More resistant bedrock - roche moutonee? or erratic? below Gribin facet in the flat area between Cwm Idwal and Cwm Bochlwyd. The flat area was eroded prior to, and during, the last glacial maximum (late Devensian) by ice flowing along the valley of Llyn Ogwen and down Nant Ffrancon. Ice movement from towards the foreground. Background shows the cliffs of the Tryfan ridge.
