Descr
Near an old stream channel, 150m to the west of the old Marble Point runway near the northern end; the site is on the flattish crest of a small hillock which forms |
part of a linear ridge system with 2 to 3m relief; the site is 4m from a patterned ground trough border |
Geoland
The surface is a gently undulating till plain formed by retreat of the Wilson Piedmont Glacier; The Marble Point region is an old landscape, as evidenced by |
deposits of phillipsite, buried soils and oxidised gneiss, which have been covered by advances of the grounded Ross Ice Shelf; later ice retreat and glaciological |
features have been controlled by changes in the stranded Wilson Piedmont Glacier; the till mantle is patchy and dominated largely by locally occurring rocks |
