Geology

Geological setting:: Ferrar Dolerite occurs extensively as sills and forms erosion resistant caps on many hills and ridges; below the main ridge thin accumulations of dolerite drift are present

Patterned ground:: Nil

Surface weathering or surface features:: Moderately developed interlocked pebble pavement with no upstanding clasts; moderately developed surface polish and moderate rounding, minor ridging may be wind ripples

Soil

Soil parent material:: Dolerite drift

Previous disturbance:: Nil

Soil weathering stage:: 6 6 (Campbell & Claridge 1975)

Soil moisture status:: Ultraxerous; some snow patches but no thawing

Biological activity:: Nil observed

Profile Description
Horizon	Depth	Description
89a	0 – 5 cm	reddish brown (5YR 5/3) gravelly pebbly sand; loose; flecks of salt throughout the horizon; rock particles mainly subangular, strongly stained, fragmental and strongly altered; distinct boundary,
89b	5 – 8 cm	yellowish red (5YR 5/8) sandy gravel; weakly cohesive; many white salt flecks; distinct boundary,
89c	8 – 18 cm	yellowish red (5YR 5/8) sandy pebbly gravel; moderately cohesive; abundant white crystalline salts concentrated in patches; rock particles subangular, fretted, strongly stained and strongly altered; distinct boundary,
89d	18 – 36 cm	strong brown (7.5YR 5/6) pebbly sandy gravel; loose; rock particles mainly subangular and moderately stained; smaller particles moderately altered but larger particles unstained and unaltered; sharp boundary, on dolerite rock
