Geology

Geological setting:
The rocks are medium to fine grained granite with little till;
Patterned ground:
Nil
Surface weathering or surface features:
The bedrock exposure has very strong cavernous weathering with up to 1.2m of rock removed; surface oxidation is well developed especially on north facing surfaces; exfoliation is the main weathering process

Soil

Soil parent material:
Granite exfoliate accumulated in hollows and clefts
Previous disturbance:
Nil
Soil weathering stage:
1 (Campbell & Claridge 1975)
Soil moisture status:
No water observed
Biological activity:
Nil observed
