Geology

Geological setting:
Cover deposits are patchy, varying from bouldery felsenmeer regolith to intermittent till; at this site, bouldery dolerite, 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

Soil

Soil parent material:
Bouldery dolerite till
Previous disturbance:
Nil
Soil weathering stage:
6 2 (Campbell & Claridge 1975)
Soil moisture status:
Ultraxerous, isolated small (<1m) patches of snow mainly behind larger boulders
Biological activity:
Nil observed
Profile Description
HorizonDepthDescription
81a 0 – 5 cm pale brown (10YR 6/3) bouldery sandy gravel; fine fraction between boulders cohesive; strongly developed vesicular structure; salt accumulations beneath surface stones; rock particles subangular to angular and moderately to strongly altered with brown stained surfaces; distinct boundary,
81b 5 – 10 cm pale brown (10YR 6/3) bouldery sandy gravel; loose to weakly cohesive; salts diffused through the horizon; subangular to angular, but moderately to strongly altered and with brown stained surfaces; indistinct boundary,
81c 10 – 25 cm pale brown (10YR 6/3) bouldery sandy gravel; loose; rock particles subangular to angular but moderately to strongly altered and with brown stained surfaces; sharp boundary, on frozen ground
