Geoland
| 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 |
Prevdist
| The site was very close to the original Scott Base buildings; the surface was subsequently modified by additilon of fill and land levelling for vehicle access to |
| existing base buildings; a range of foreign materials are present but occur mainly at the surface |
