Demas Range

The Demas Range (-75°N, -133.75°W) is a range about 8 nmi 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, 1115 m high.

Location
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.

Discovery and naming
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.

Holmes Bluff

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.

Kennel Peak
-75.01667°N, -133.73333°W. A small but notable rock peak over 800 m high about 0.5 nmi 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.

Rockney Ridge
-75.03333°N, -133.75°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.

Mount Goorhigian
-75.05°N, -133.76667°W. The highest mountain, 1,115 m 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.

Kouperov Peak
-75.1°N, -133.8°W. A peak 890 m 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.

Shibuya Peak
-75.16667°N, -133.58333°W. A rocky summit 840 m high on the east  side of Berry Glacier, 4 nmi southeast  of Demas Range. Mapped by USGS from surveys and United States Navy air photos, 1959-65. Named by US-ACAN for Franklin T. Shibuya, USARP meteorologist at Byrd Station, 1962.

Patton Bluff
-75.21667°N, -133.66667°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.

Cousins Rock
-75.26667°N, -133.51667°W. An isolated rock located eastward of the upper part of Berry Glacier and Patton Bluff, about 3.5 nmi 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.

Coleman Nunatak
-75.31667°N, -133.65°W. A nunatak located near the head of Berry Glacier, 2 nmi south of Patton Bluff. Mapped by USGS from surveys and United States Navy air photos, 1959-65. Named by US-ACAN after Richard I. Coleman, USARP meteorologist at Byrd Station, 1962.
