Geology

Geological setting:
Rocks are predominantly scoria flows of the McMurdo Volcanics; Last Glaciation Ross 1 ice covered the site and traces of rocks (sandstone and granite granules and small pebbles) probably from the Royal Society Range can be found; the drift mantle is thin and patchy with bedrock a little below the surface
Patterned ground:
Nil
Surface weathering or surface features:
Nil

Soil

Soil parent material:
Drift deposit from McMurdo Volcanics, with some surface modification and site levelling from base site occupation
Previous disturbance:
Disturbed surface with numerous items of anthropic debris, wood fragments, fibres; plastics etc
Soil weathering stage:
6 1 (Campbell & Claridge 1975)
Soil moisture status:
Some surface thaw water during summer; currently dry but frozen to the surface
Biological activity:
Nil
