Шаблон:Infobox mountain The Bermel Escarpment (Шаблон:Coord ) is a snow and rock escarpment, Шаблон:Convert long, extending from the base of the Ford Massif to King Peak, in the Thiel Mountains of Antarctica. The escarpment drops Шаблон:Convert from the Antarctic Plateau to the ice surface north of these mountains.Шаблон:Sfn

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).Шаблон:Sfn

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.Шаблон:Sfn

Taylor Outlier

Шаблон:Coord. A relatively isolated rock lying just in front of the west end of the Bermel Escarpment and about Шаблон:Convert east of the lower part of Counts Icefall. Mapped by USGS from surveys and United States Navy air photos, 1959-61. Named by US-ACAN for Alfred R.

Named for Rowland Tabor, USGS geologist with the 1961-62 Thiel Mountains party.Шаблон:Sfn

Elliot Nunatak

Elliott, geologist with the Thiel Mountains party.Шаблон:Sfn

Drake Nunatak

Шаблон:Coord. A nunatak, Шаблон:Convert high, at the base of Bermel Escarpment and Шаблон:Convert east of Elliott Nunatak. The name was proposed by Arthur Ford and Peter Bermel, co-leaders of the USGS Thiel Mountains party of 1960-61. Named for Avery A. Drake, Jr., USGS geologist aboard the USS Glacier to the Thurston Island and Bellingshausen Sea area, 1960-61.Шаблон:Sfn

Hayes Peak

Шаблон:Coord. An isolated, low rock peak, Шаблон:Convert high, rising above the ice surface just south of Bermel Escarpment. The name was proposed by Peter Bermel and Arthur Ford, co-leaders of the USGS Thiel Mountains party which surveyed these mountains in 1960-61. Named for Philip T. Hayes, USGS geologist in the McMurdo Sound dry valley area, 1958-59.Шаблон:Sfn

King Peak

Шаблон:Coord. A rock peak, Шаблон:Convert high, surmounting the east extremity of the Bermel Escarpment, Шаблон:Convert west-northwest of Mount Powell The name was proposed by Peter Bermel and Arthur Ford, co-leaders of the USGS Thiel Mountains party which surveyed these mountains in 1960-61. Named for Clarence King, the first director of the US Geological Survey, 1879-81. Other peaks in the vicinity are named for subsequent directors of the USGS.Шаблон:Sfn

Southern massif

The names of features in this massif were proposed by Peter Bermel and Arthur Ford, co-leaders of the USGS Thiel Mountains party which surveyed these mountains in 1960-61.

Mount Powell

Шаблон:Coord. A prominent mountain, Шаблон:Convert high, sharing a small massif with King Peak which stands Шаблон:Convert west-northwest. Named for John Wesley Powell, second director of the United States Geological Survey, 1881-94.Шаблон:Sfn

Mount Walcott

Шаблон:Coord. A mainly ice-free mountain, Шаблон:Convert high, located Шаблон:Convert east of Mount Powell. Named for Charles Doolittle Walcott, third director of the United States Geological Survey, 1894-1907.Шаблон:Sfn

Mount McKelvey

Шаблон:Coord. A rocky, mostly ice-free peak, Шаблон:Convert high, situated less than Шаблон:Convert east of Mount Walcott in the eastern portion of the Thiel Mountains. Surveyed by the USGS Thiel Mountains party, 1960-61. Named by US-ACAN for Vincent E. McKelvey, ninth director of the U.S. Geological Survey, 1971-78. During this period numerous USGS geologic and topographic expeditions, for which he had administrative responsibility, were carried out in Antarctica.Шаблон:Sfn
