Descr
| To the north of an un-named peak (Pk 2421) to the SE of Turnstile Ridge and west of the head of the Hatherton Glacier on the moraine covered floor of a big |
| basin; a valley floor moraine to the SE of the basin glacier, an old moraine surface approximately 4.5km NNE of Pk 2421; a slightly hollowed topography that |
| may be partly wind sculptured |
Geoland
| Ferrar Dolerite outcrops on the high surfaces; the soils on the high surfaces show significant weathering and the tills on the lower surfaces probably include |
| much reworked and pre weathered material; on the northern slopes of the basin, the till deposits are probably old cirque moraines that may have been partly |
| sorted by wind resulting in gravel dunes |
