| Ferrar Dolerite caps the ridges and forms a prominent escarpment marking the edge of the Polar Plateau; a former more extensive Polar Ice Sheet would have |
| extended in icefalls over the escarpment; the valleys on the SW side of the Hatherton Glacier appear to form an old landscape; moraine sequences reflect the |
| advances from the Hatherton Glacier; some depressions in the landscape may have been former salty hollows |
