Bear Peninsula
Bear Peninsula (74°35′S 111°00′W / 74.583°S 111.000°W) is a peninsula about 50 nautical miles (93 km; 58 mi) long and 25 nautical miles (46 km; 29 mi) wide which is ice-covered except for several isolated rock bluffs and outcrops along its margins, lying 3 nautical miles (5.6 km; 3.5 mi) east of Martin Peninsula on Walgreen Coast, Marie Byrd Land, Antarctica.
The Bear Peninsula extends in a northeast direction from the Walgreen Coast of Marie Byrd Land between the Dotson Ice Shelf to the west and Smith Glacier and the Crosson Ice Shelf to the southeast. The north of the peninsula extends into the Amundsen Sea. The Thwaites Iceberg Tongue is to the northeast. Western features include, from south to north, Boschert Glacier, Hayden Peak, Gerrish Peaks, True Glacier, Hunt Bluff, Mount Bodziony, Zuniga Glacier, Jeffrey Head, Brush Glacier, Webster Pass, Rogers Spur and Sorenson Glacier. Northern features include, from west to east, Moore Dome, Koloc Point, Park Glacier, Harmon Bay, Gurnon Peninsula, Garwood Point and Hummer Point. Eastern features include, from north to south, Bunner Glacier, Hamilton Ice Piedmont, Merrick Point, Wyatt Hill, Grimes Ridge, Goepfert Bluff, Holt Glacier, Wright Pass, Jones Bluff, Barnes Bluff, Eckman Bluff and Mayo Peak.
The Bear Peninsula was first delineated from aerial photographs taken by the United States Navy Operation Highjump in January 1947. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) after the ice-ship USS Bear, flagship of the USAS, from which three reconnaissance flights were made in late February 1940, resulting in the discovery of Walgreen Coast (with probable sighting of this feature) and the Thurston Island area. This ship, under the name Bear of Oakland, also served as flagship of the Byrd AE, 1933–35, which based at the Bay of Whales, Ross Ice Shelf. Launched in 1874 at Greenock, Scotland, for use in the sealing trade, she sank in 30-foot seas and high winds in the North Atlantic, March 19, 1963, at which time she was being towed from Nova Scotia to Philadelphia.
Glaciers that drain from the peninsula into the surrounding ice shelves or open sea include, clockwise from the southwest:
74°43′S 111°30′W / 74.717°S 111.500°W. A glacier to the southeast of Hayden Peak, flowing southwest from Bear Peninsula into Dotson Ice Shelf. Mapped by USGS from United States Navy aerial photographs taken 1966. Named in 1977 by US-ACAN after Ralph G. Boschert, USGS cartographer, a member of the United States Geological Survey (USGS) satellite surveying team at South Pole Station, winter party 1975.
74°38′S 111°45′W / 74.633°S 111.750°W. A glacier on the west side of Bear Peninsula, flowing southwest into Dotson Ice Shelf south of Hunt Bluff. Mapped by USGS from United States Navy aerial photographs taken in 1966. Named by US-ACAN in 1977 after Lawrence E. True, United States Navy radioman who to that time had served in three deployments of OpDFrz.
74°34′S 111°51′W / 74.567°S 111.850°W. A glacier flowing west-northwest into Dotson Ice Shelf between Jeffrey Head and Mount Bodziony on the west side of Bear Peninsula. Mapped by USGS from aerial photographs taken by United States Navy OpHjp in 1947 and United States Navy in 1966. Named by US-ACAN after Mike Zuniga, Chief Aviation Storekeeper, United States Navy, who made seven Deep Freeze deployments between 1960 and 1978.
74°29′S 111°36′W / 74.483°S 111.600°W. A broad glacier in the northwest part of Bear Peninsula, flowing west into Dotson Ice Shelf to the north of Jeffrey Head. First mapped by USGS from air photos taken by United States Navy OpHjp in January 1947. Named by US-ACAN for Bernard E. Brush, station engineer at the Byrd (very low frequency) Substation, 1966.
