Geology
Geological setting:
Till deposited in a small glacial basin and derived from principally greywacke rocks of the Robertson Bay Group, some minor fluvial and patterned ground sediment reworking
Patterned ground:
Moderately developed nets 1-2m across with stone borders
Surface weathering or surface features:
Surface clasts subangular and unweathered but splitting along cleavage planes,
Soil
Soil parent material:
Loose till, mainly greywacke with some felsite, possibly some loessial material
Previous disturbance:
Nil
Soil weathering stage:
6
Soil moisture status:
Oceanic subxerous, some moisture from thawing of patchy snow cover with seepage to lower lying sites
Biological activity:
Moss and lichen patches in small discontinuous patches around edges of surface rocks in moist hollows
