Geology

Geological setting:

Several prominent bench surfaces above Taylor Glacier may mark former glacial erosion surfaces; weathering increases with increasing elevation; this surface has a stony till cover with few large surface boulders and the till is from predominantly dolerite

Patterned ground:

Nil

Surface weathering or surface features:

The pavement is dominantly cobble and small boulders and moderately developed but weakly ventiform; some surface boulders are well fractured with coarser clasts showing granular disintegration; granite shows some minor cavernous weathering but strong granular disintegration; clast staining is moderate

Soil

Soil parent material:

Bouldery doleritic till with some granite and sandstone

Previous disturbance:

Nil

Soil weathering stage:

6 4 (Campbell & Claridge 1975)

Soil moisture status:

A dry site with no snow patches

Biological activity:

Nil observed
