Striae and former ice-flow directions in Snowdonia, North Wales
There are two views concerning the mountains of Snowdonia and their role during former glaciations of Britain. One is that they formed a subsidiary centre for ice dispersal, while the second is that they were overrun by westward-flowing ice derived from the main Welsh ice centre in the east. In this...
