Demas Range
The Demas Range (75°0′S 133°45′W / 75.000°S 133.750°W) is a range about 8 nautical miles (15 km; 9.2 mi) long that forms the lower east margin of the Berry Glacier in Marie Byrd Land, Antarctica. The range trends north–south culminating in Mount Goorhigian, 1,115 metres (3,658 ft) high.[1]

Location edit
The Demas Range is northeast of the Ames Range and east of the Perry Range, from which it is separated by the Berry Glacier. It is west of the DeVicq Glacier. It extends north to the Getz Ice Shelf. Features, from north to south, include Holmes Bluff, Kennel Peak, Rockney Ridge, Mount Goorhigian and Kouperov Peak. Features further south, to the east of the Berry Glacier, include Shibuya Peak, Patton Bluff, Cousins Rock and Coleman Nunatak.[2][3]
Discovery and naming edit
The Demas Range was discovered by the United States Antarctic Service (USAS), 1939–1941, led by Admiral Richard E. Byrd. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for E.J. "Pete" Demas, a member of the Byrd Antarctic Expeditions of 1928–1930 and 1933–1935.[1]
Features edit
Holmes Bluff edit
74°59′S 133°43′W / 74.983°S 133.717°W. A bluff marking the north end of Demas Range. The feature was observed from aircraft of the United States Antarctic Service, 1939-41, but was first mapped in detail by the United States Geological Survey (USGS), 1959-65. Named by US-ACAN for Thomas J. Holmes, USARP meteorologist at Byrd Station, 1961.[4]
Kennel Peak edit
75°01′S 133°44′W / 75.017°S 133.733°W. A small but notable rock peak over 800 metres (2,600 ft) high about 0.5 nautical miles (0.93 km; 0.58 mi) north of Rockney Ridge. Mapped by USGS from surveys and United States Navy air photos, 1959-69. Named by US-ACAN for A. Alexander Kennel, ionospheric physicist, Station Scientific Leader at South Pole Station, 1969.[5]
Rockney Ridge edit
75°02′S 133°45′W / 75.033°S 133.750°W. A rock ridge on the northeast side of Mount Goorhigian. Mapped by USGS from surveys and United States Navy air photos, 1959-65. Named by US-ACAN for Vaughn D. Rockney, meteorologist at Byrd Station, 1968-69.[6]
Mount Goorhigian edit
75°03′S 133°46′W / 75.050°S 133.767°W. The highest mountain, 1,115 metres (3,658 ft) high, of the Demas Range. Mapped by USGS from surveys and United States Navy air photos, 1959-65. Named by US-ACAN after Martin Goorhigian, USARP meteorologist at Byrd Station, 1961.[7]
Kouperov Peak edit
75°06′S 133°48′W / 75.100°S 133.800°W. A peak 890 metres (2,920 ft) high at the south end of the Demas Range. Mapped by USGS from surveys and United States Navy air photos, 1959-65. Named by US-ACAN for Leonid Kouperov, Soviet Exchange Scientist (ionospheric physicist) to the United States Byrd Station, 1961.[8]

75°13′S 133°40′W / 75.217°S 133.667°W. A bluff situated between Shibuya Peak and Coleman Nunatak on the east side of Berry Glacier. Mapped by USGS from surveys and United States Navy air photos, 1959-65. Named by US-ACAN for Delbert E. Patton, USARP ionospheric physicist at Byrd Station, 1962.[10]
Cousins Rock edit
75°16′S 133°31′W / 75.267°S 133.517°W. An isolated rock located eastward of the upper part of Berry Glacier and Patton Bluff, about 3.5 nautical miles (6.5 km; 4.0 mi) northeast of Coleman Nunatak. Mapped by USGS from surveys and United States Navy air photos, 1959-65. Named by US-ACAN for Michael D. Cousins, ionospheric physicist at Siple Station, 1969-70.[11]
