The Moulton Escarpment trends east to west, with outcrops rising above the ice for 4.5 kilometers. This is the westernmost nunatak in the Thiel Mountains. Approximately 25 square kilometers of ice is exposed in the area.
Ice appears to flow from south to north.
The larger ice areas are situated upstream and downstream of the escarpment, but smaller ice patches occur to the west and east along the ice escarpment. Figure 35 is a vertical aerial photograph mosaic of the Moulton Escarpment. Reconnaissance during the 1982-1983 season failed to find meteorites on the upstream icefield. One meteorite was found on the isolated ice patch to the east. Meteorites were also found in a restricted area below the escarpment and east of the ice-cored moraines.
