The materials comprise volcanics of the McMurdo Volcanics Formation mainly as scoriaceous lava flows; the surface materials are a thin cover of mainly |
fractured bedrock with addition of some glacially derived granular and pebble clasts from outside the immediate area; the volcanic bedrock has been |
considerably fractured by patterned ground freeze thaw; the surface age is probably very late Pleistocene (Ross Sea Glaciation) having been modified by |
McMurdo Sound filling glacial ice |
