Descr
Between Scott base and Crater Hill just north of west, a small nivation cirque above and southwest of a bend in the track to a US radio antennae facility; this site |
is the first of 5 sites sampled in sequence from beneath a snow bank to about 15m beyond to examine soil moisture relationships adjacent to a snow source; this |
site is underneath a patch of 'permanent' (but retreating) snow |
Geoland
Rocks are predominantly scoria flows of the McMurdo Volcanics; Last Glaciation Ross 1 ice covered the site and traces of rocks (sandstone and granite granules |
and small pebbles) probably from the Royal Society Range can be found; the drift mantle is thin and patchy with bedrock a little below the surface; the ground |
surface is covered with permanent snow |
