# Cooper Snowfield

Cooper Snowfield (80°56′S 158°40′E﻿ / ﻿80.933°S 158.667°E﻿ / -80.933; 158.667) is a snowfield with an area of about 25 square miles (65 km$^2$) in the Churchill Mountains of Antarctica.

## Location

The snowfield rises to over 1,200 metres (3,900 ft) and is nearly encircled by ridges connecting Mount Field, Mount Durnford, and Mount Liard. It was named after Alan K. Cooper, a marine geophysicist with the United States Geological Survey, Menlo Park, California, who was involved in drilling and seismic studies of the Antarctic continental margin for deriving paleoenvironments and ice sheet history, 1984–2002.

## Surrounding features

The snowfield is bordered by the Skinner Saddle to the east. Surrounding mountains clockwise from the southeast are Mount Liard, Mount Stewart, Mount Durnford, Mount Field, Mount Hubble.

### Mount Liard

80°58′S 158°51′E﻿ / ﻿80.967°S 158.850°E﻿ / -80.967; 158.850. A peak 6 nautical miles (11 km) east of Mount Durnford. It rises to 1,770 metres (5,800 ft) on the ridge south of Cooper Snowfield. The peak was named by the Advisory Committee on Antarctic Names after Theodore J. Liard, Jr. (1918–2002), a geographer with the Department of Interior and the Department of Defense in toponymic research for the U.S. Board on Geographic Names, 1949–80. Liard was Chief of the Geographic Names Division at the Defense Mapping Agency, 1969–80.

### Mount Stewart

Named in honor of Ian Stewart, a retired diplomat, who was also the Whaling Commissioner for 12 years before John Scott and Jim McLay, setting the groundwork in place.

### Mount Durnford

80°58′S 158°15′E﻿ / ﻿80.967°S 158.250°E﻿ / -80.967; 158.250. A mountain, 2,715 metres (8,907 ft) high, standing 5 miles (8.0 km) southeast of Mount Field. Discovered and named "Durnford Bluff by the BrNAE (1901-04), for Admiral Sir John Durnford, a Junior Naval Lord who was of assistance to the expedition. The NZGSAE (1960-61) remapped the feature and amended the name to Mount Durnford. Not: Durnford Bluff.

### Mount Field

80°53′S 158°02′E﻿ / ﻿80.883°S 158.033°E﻿ / -80.883; 158.033. A mountain, 3,010 metres (9,880 ft) high, standing 3 miles (4.8 km) south-south-east of Mount Egerton. Discovered and named by the BrNAE, 1901-04, under Scott.

### Mount Hubble

80°52′S 158°19′E﻿ / ﻿80.867°S 158.317°E﻿ / -80.867; 158.317 A mountain rising to 2,490 metres (8,170 ft) between Mount Field and Mount Dick. It was named after American astronomer Edwin Hubble of the Carnegie Institution of Washington's Mount Wilson Observatory, 1919–53; in 1923 he furnished the first certain evidence that extragalactic nebulae were situated far outside the boundaries of our own galaxy, in fact were independent stellar systems.

## Northern peaks

To the north of Mount Field and Mount Hubble are Mount Egerton, East Egerton, Mount Dick and Prior Cliff

### Mount Egerton

80°50′S 157°55′E﻿ / ﻿80.833°S 157.917°E﻿ / -80.833; 157.917. A mountain, 2,830 metres (9,280 ft) high, rising 3 miles (4.8 km) north-north-west of Mount Field.

### East Egerton
