| Xerous to subxerous; soil is moist below the surface; some moisture derived from small |

Coastal mountain
Fragmented bouldery volcanic bedrock with some additions of glaciogenic finer materials, in part with some modification by slope drift processes
A few small patches of yellow lichen and some moss in the general vicinity
Weakly developed and without distinctive trough expression or well developed net pattern
| SURFACE WEATHERING or |
| SURFACE FEATURES |
| Surface boulder clasts show some slight wind polish but no surface oxidation; pavement between larger clasts is dominantly granular-pebble sized; some |
| thin surface salt accumulations occur near wet patches formed by snow melt |
| No evidence of past mechanical disturbance at the immediate trial site area but moderate foot traffic disturbance is very likely; present disturbance includes |
| the presence of numerous particles of introduced organic and inorganic materials |

Descr
| A gently sloping area forming a small bench on a moderately steep slope between Crater Hill and the east coast of Ross Island approximately 150m northwest |
| from the Scott base buildings; drill hole and access tube site located in the NE corner of the southern undisturbed part of an experimental area near the edge of a |
| small transient snow bank |
Geoland
| The deposit comprises volcanics of the McMurdo Volcanics Formation mainly as scoriaceous flows; the surface materials are a thin cover of mainly fractured |
| bedrock with addition of glacially derived granular and pebble clasts from outside the immediate area; the volcanic bedrock has been considerably fractured by |
| freeze thaw; the surface age is probably very late Pleistocene (Ross Sea Glaciation) having been modified by McMurdo Sound filling glacial ice |
