Geology

Geological setting:
Valley head tills mark successive retreat stages of the Scott Glacier; being furthermost from the ice edge, on the valley side above the tills, weathering and surface age appears to increase; calcium carbonate occurs on till with predominantly granitic rocks
Patterned ground:
Weakly to moderately developed
Surface weathering or surface features:
Rocks mainly angular but some weak surface staining

Soil

Soil parent material:
Bouldery granitic till
Previous disturbance:
Nil
Soil weathering stage:
6
Soil moisture status:
Occasional small snow patches
Biological activity:
