| A moraine filled basin, north of the terminus of the Foggydog Glacier and west of the Bartrum Glacier with a series of distinct moraine loops, formed by the |
| retreat of the two glaciers; the is site flat, on one of the furthermost loops of the Bartrum Glacier and is towards the edge of a polygon |
Geoland
| Granite Harbour Intrusives and dolerite sills occur widely on surrounding mountains; the till is dominantly granitic with minor dolerite but some schist is |
| present; the till sequence reflects the deposition of moraines in association with retreat of the Foggydog and Bartrum Glaciers |
