Geology

Geological setting:
The moraine at this site forms a tongue on the floor of a narrow valley as a result of retreat of a local alpine glacier; the till is locally derived from dolerite and Beacon Group sediments and is younger than that on which soil 69 is formed
Patterned ground:
Well developed 5-10m polygonal nets with 50-75cm troughs
Surface weathering or surface features:
Surface cobbles and boulders are mainly unstained and subangular to angular

Soil

Soil parent material:
Till derived mainly from dolerite and Beacon Group sedimentary rocks
Previous disturbance:
Nil
Soil weathering stage:
6 1 (Campbell & Claridge 1975)
Soil moisture status:
Xerous; snow filling most patterned ground depressions and some frozen water accumulations in a few small hollows
Biological activity:
Nil observed
