Geology
Geological setting:
Granite and dolerite outcrop with oxidised and exfoliated granite occurring on elevated knolls; occasional dolerite erratics are present; the surface is clearly much older than those of the lower altitude moraine sequences
Patterned ground:
Nil
Surface weathering or surface features:
Rounded and exfoliated bedrock with distinctly oxidised surfaces; a few scattered pitted dolerite erratics; salts beneath some surface stones
Soil
Soil parent material:
Disaggregated fine-grained biotite granite with occasional dolerite erratics
Thin patchy snow cover but no liquid snow melt observed
Biological activity:
Nil at site
