Descr
Approximately 350m northwest of the western end of Scott Base in the floor of a shallow gully, 20m NW of site 587 and 3-4m lower in altitude; about 50m |
north of the Scott Base to McMurdo Station; at this site, 4 contiguous 1m X 1m plots were set out and 3 irrigated with LiCl, the 4th (northernmost) with H2O; |
this sampling was from 1m down slope from the first application plot |
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 |
