Geology

Geological setting:
Cover deposits are patchy, varying from bouldery felsenmeer regolith to intermittent till; at this site, bouldery dolerite till comprising mainly angular flaggy clasts, covers the surface
Patterned ground:
10m domed nets with 50cm deep border troughs
Surface weathering or surface features:
Boulders are mainly subangular and flaggy with only slight rounding on corners; weak to moderate surface staining with no pitting or exfoliation; salts beneath surface stones; some accumulations of browner coloured soil material occur beneath some surface stones and in some cracks between surface rocks

Soil

Brown patches of doleritic soil with salt accumulations, beneath surface stones and in some cracks between surface rocks
Previous disturbance:
Nil
Soil weathering stage:
6
Soil moisture status:
Ultraxerous, isolated small (<1m) patches of snow mainly behind larger boulders
Biological activity:
