The Bermel Escarpment is a snow and rock escarpment, 15 nmi long, extending from the base of the Ford Massif to King Peak, in the Thiel Mountains of Antarctica. The escarpment drops 300 to from the Antarctic Plateau to the ice surface north of these mountains.

Discovery and naming

The Bermel Escarpment was named by the United States Advisory Committee on Antarctic Names (US-ACAN) after Peter F. Bermel, a cartographer with the United States Geological Survey (USGS). Bermel was co-leader (with Arthur B. Ford) of the USGS Thiel Mountains party which surveyed the mountains in 1960–61, and also leader of USGS Topo East and Topo West, 1962–63, in which geodetic control was extended from the area of Cape Hallett to the Wilson Hills (Topo West), and from the foot of Beardmore Glacier through the Horlick Mountains (Topo East).

Location

The Bermel Escarpment extends southeast from the Counts Icefall, which separates it from the Ford Massif to the north. It faces northeast, dropping from the polar plateau. Features from northwest to southeast include Taylor Outlier, Tabor Spur, Elliot Nunatak, Drake Nunatak and King Peak. A small massif extends the escarpment to the south and includes Mount Powell, Mount Walcott, Mount Wrather, Mendenhall Peak, Smith Knob and Nolan Pillar.
