Geology
Geological setting:
Deposits on low surfaces near the coast are fluvially worked volcanic materials from adjacent outcrops of McMurdo Volcanics; beach deposits nearest the coast merge into and are overlain by less well sorted and rounded material
Patterned ground:
Nil
Surface weathering or surface features:
Weakly developed pavement of subrounded basaltic pebbles and cobbles; some salts beneath surface stones
Soil
Soil parent material:
Weakly stratified colluvium derived from basalt flow, scoria and tuffite; partly sorted and rounded
Oceanic subxerous, soil moisture derived from occasional snowfalls and from windblown snow
Biological activity:
Scattered lichen patches
