Some small patches of salt are present within a metre of the site; the surface is just outside of vehicle access areas; foreign materials include copper cable
The land surface was shaped at the time of construction of the field store building; probably minimal disturbance since apart from activities around the field |

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 |
