Geology
- Geological setting:
- Local rocks are Beacon Sandstone and Ferrar Dolerite; the till in the valley floor contains granite with some large erratics near the valley mouth from outside the region; the erratics indicate former incursions of ice into the valley mouth; moraine loops show the extent of various ice advances
- Patterned ground:
- Nil
- Surface weathering or surface features:
- Some granite boulders strongly oxidised and crumbled, others with a fresher appearance; well developed cavernous weathering; dolerite strongly stained and pitted; well developed pavement with polish and ventiforms; abundant salts beneath surface stones
Soil
- Soil parent material:
- Dolerite and sandstone till with some granite forming paleosols
- Previous disturbance:
- Nil
- Soil weathering stage:
- 6 4 (Campbell & Claridge 1975)
- Soil moisture status:
- Xerous to subxerous; occasional light summer snow falls with brief surface soil moistening
- Biological activity:
- Nil at site
