Geological setting:
Ferrar Dolerite caps the ridges and forms a prominent escarpment marking the edge of the Polar Plateau; a former more extensive Polar Ice Sheet would have extended in icefalls over the escarpment; the surfaces and the soils around the edge of the escarpment at Derrick Peak provide an indication of when the Polar Ice Sheet last extended across the escarpment and into the valleys of the Hatherton Glacier; till at this site includes some sandstone
Patterned ground:
Very weakly developed
Surface weathering or surface features:
Coarse grained dolerite boulders well rounded and upstanding to 40cm; some cavernously weathered; staining is strong with active surface and weathering rhind exfoliation; fine grained rocks strongly stained and pitted; sandstone clasts stained and case hardened; some moderately developed ventiforms; salts beneath a few surface stones; a strongly developed pavement


Soil parent material:
Stony till predominantly from dolerite but with some sandstone
Previous disturbance:
Soil weathering stage:
6 4/5 (Campbell & Claridge 1975)
Soil moisture status:
Extensive snow cover but no thaw observed or soil moistening
Biological activity:
Nil observed
Profile Description
448a -2 – 0 cm surface small cobbles, pebbles and granular sand; rock particles strongly stained and many pitted; some particles with red (2.5Y 4/8) amorphous intergranular fillings; salts beneath stones,
448b 0 – 8 cm brown (7.5YR 5/4) sandy granular gravel; loose; rock particles subangular, moderately stained and moderately altered; sharp boundary,

448d 15 – 30 cm strong brown (7.5YR 5/6) sandy cobbly to bouldery gravel; moderately to strongly cohesive; scattered salt flecks; larger rock particles angular and unstained; smaller particles subangular to subrounded, weakly stained and weakly altered; indistinct boundary,
448e 30 – 62 cm strong brown (7.5YR 5/6) sandy bouldery gravel; loose to weakly cohesive; salt precipitations on a few rock faces; larger rock particles angular to subangular and unstained but smaller particles subrounded; indistinct boundary,
448f 62 – 75 cm strong brown (7.5YR 5/8) bouldery sandy gravel; loose; pulverulent
