Geology
Geological setting:
Ferrar Dolerite sills outcrop with Beacon Group sediments, these rocks forming the main components of the tills which mantle most of the lower slopes; surface features suggest there may have been some slight solifluction movement
Patterned ground:
Weakly developed nets with 20cm troughs; some contraction cracks in profile pits are without surface expression
Surface weathering or surface features:
Subrounded to subangular dolerite cobbles and pebbles with moderate surface staining; some small salt patches beneath surface stones
Soil
Soil parent material:
Stony till comprising mainly dolerite and some fine grained sedimentary rocks
light brown (7.5YR 6/4) pebbly gravel; moderately cohesive; aggregates formed through coating with fines; moderately developed vesicular structure; rock particles subangular to subrounded and weakly stained; distinct boundary,
