Geology

Geological setting:
Dolerite outcrops widely in an undulating ice overridden landscape; cover deposits are patchy varying from bouldery felsenmeer regolith to intermittent till patches; surface age is variable owing to remnant snow fields which behave as local nevee glaciers; the drift mantle is young but may include previously weathered materials
Patterned ground:
Ice cored moraine with low (<1m) mounds, in places forming low ridges
Surface weathering or surface features:
Some exfoliation of surface boulders but may be preweathering

Soil

Soil parent material:
A small patch of fine textured yellow coloured drift
Previous disturbance:
Nil
Soil weathering stage:
6
Soil moisture status:
Ultraxerous, intermittent snow cover but no thawing observed
Biological activity:
Nil observed
