Descr
| About 50m from the western side of the old runway, towards the northern end on a surface which has been cut and scraped for construction materials, an uneven |
| surface with linear cut and sidecast ridges; the surface forms a hollow, about 75cm below original ground surface and probably accumulates some thaw water at |
| times |
Geoland
| The land 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 |
