Mitchell Peninsula ( 66°20′S110°32′E / 66.333°S 110.533°E ) is a rocky peninsula, 2.5 nautical miles (5 km) long and 2 nautical miles (4 km) wide, lying between O'Brien Bay and Sparkes Bay at the east side of the Windmill Islands, Antarctica. It was first mapped from aerial photographs taken by U.S. Navy Operation Highjump in February 1947 and thought to be an island connected by a steep snow ramp to the continental ice overlying Budd Coast, though the term peninsula was considered more appropriate by the Wilkes Station party of 1957. Mitchell Peninsula was named by the Advisory Committee on Antarctic Names for Captain Ray A. Mitchell, U.S. Navy, captain of the USS Cacapon, a tanker of the western task group of Operation Highjump, Task Force 68 of 1946–47. [1]
On its southern side is Bednarz Cove, and Drew Cove indents the west side.
Thurston Island is a largely ice-covered, glacially dissected island, 135 nautical miles long and 55 nautical miles wide, lying between Amundsen Sea and Bellingshausen Sea a short way off the northwest end of Ellsworth Land, Antarctica. The island is separated from the mainland by Peacock Sound, which is occupied by the west portion of Abbot Ice Shelf.
Mount Murphy is a massive, snow-covered mountain with steep, rocky slopes rising to 2,505 metres (8,219 ft) in Marie Byrd Land, Antarctica. It is directly south of Bear Peninsula and is bounded by Smith Glacier, Pope Glacier and Haynes Glacier. Volcanic activity began in the Miocene with the eruption of basaltic and trachytic lava. Volcanism on the slopes of the volcano resumed much later during the Pleistocene, with a parasitic cone having been K–Ar dated to 0.9 million years old.
Bear Peninsula is a peninsula about 50 nautical miles long and 25 nautical miles wide which is ice-covered except for several isolated rock bluffs and outcrops along its margins, lying 3 nautical miles east of Martin Peninsula on Walgreen Coast, Marie Byrd Land, Antarctica.
Martin Peninsula is a peninsula about 60 nautical miles long and 20 nautical miles wide that is ice-covered except for a few rock outcrops along its margins, located between Getz Ice Shelf and Dotson Ice Shelf on the coast of Marie Byrd Land, Antarctica. The farthest point of the peninsula is Jacobsen Head.
The Getz Ice Shelf is an ice shelf over 300 nautical miles long and from 20 to 60 nautical miles wide, bordering the Hobbs Coast and Bakutis Coast of Marie Byrd Land, Antarctica, between the McDonald Heights and Martin Peninsula. Several large islands are partially or wholly embedded in the ice shelf.
King Peninsula is an ice-covered peninsula, 100 nautical miles long and 20 nautical miles wide, lying south of Thurston Island and forming the south side of Peacock Sound, Antarctica. It projects from the continental ice sheet and trends west between the Abbot Ice Shelf and Cosgrove Ice Shelf to terminate at the Amundsen Sea.
Browning Peninsula is a rocky peninsula, 4 miles (6.4 km) long, separating Penney Bay and Eyres Bay at the south end of the Windmill Islands. It was first mapped from air photos taken by U.S. Navy Operation Highjump and Operation Windmill in 1947 and 1948. It was named by the Advisory Committee on Antarctic Names for Commander Charles L. Browning, U.S. Navy, chief staff officer with Operation Windmill and later staff officer with Task Force 43, the logistic arm of U.S. Navy Operation Deep Freeze, 1955–56.
Clark Peninsula is a rocky peninsula, about 3 km (2 mi) long and wide, lying 5 km (3 mi) north-east of Australia's Casey Station at the north side of Newcomb Bay on the Budd Coast of Wilkes Land in Antarctica.
O'Brien Bay is a bay lying between Bailey Peninsula and Mitchell Peninsula on the Budd Coast. First mapped from air photos taken by U.S. Navy Operation Highjump and Operation Windmill in 1947 and 1948. Named by the Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant Clement E. O'Brien, United States Navy, communications officer with U.S. Navy Operation Windmill which established astronomical control stations in the Windmill Islands in 1948.
The Alexander Nunataks are two coastal nunataks at the southern limit of the Windmill Islands, standing on the shore of Penney Bay 0.4 nautical miles (0.7 km) east of the base of the Browning Peninsula. They were first mapped from air photos taken by U.S. Navy Operation Highjump and Operation Windmill in 1947 and 1948, and named by the Advisory Committee on Antarctic Names for Photographer's Mate H.N. Alexander, a member of one of the two Operation Windmill photographic units that obtained air and ground photos of the area in January 1948.
Bednarz Cove is a cove in the south side of Mitchell Peninsula on Budd Coast. It was first mapped from air photos taken by U.S. Navy Operation Highjump and Operation Windmill in 1947 and 1948, and named by the Advisory Committee on Antarctic Names for Chief Electronics Technician Donald F. Bednarz, U.S. Navy, a member of the Wilkes Station party of 1958.
Nicholson Island is the westernmost of the Bailey Rocks, lying 0.1 nautical miles (0.2 km) northeast of Budnick Hill in Newcomb Bay, Windmill Islands. First mapped from air photos taken by U.S. Navy Operation Highjump, 1946–47. Named by Antarctic Names Committee of Australia (ANCA) for R.T. Nicholson, senior carpenter, who took a leading part in the construction of nearby Casey Station in 1966.
Cranton Bay is a bay about 20 nautical miles long and wide, lying south of the Canisteo Peninsula, Antarctica, at the eastern end of the Amundsen Sea. The southern limit of the bay is formed by the Backer Islands and an ice shelf which separates this bay from Pine Island Bay.
Currituck Island is an island in Antarctica 7 nautical miles (13 km) long marked by numerous small coves, lying on the northwest side of Edisto Channel in the Highjump Archipelago. It was mapped from air photos taken by U.S. Navy Operation Highjump in February 1947, and named by the Advisory Committee on Antarctic Names in 1956 after the USS Currituck, a seaplane tender and flagship of the western task group of U.S. Navy Operation Highjump, Task Force 68, 1946–47. At that time, the northern portion was thought to be a separate feature and was named "Mohaupt Island," but subsequent Soviet Expeditions (1956–57) found that only one large island exists.
Drew Cove is a cove indenting the west side of Mitchell Peninsula on the Budd Coast. It was first mapped from air photos taken by U.S. Navy Operation Highjump and Operation Windmill in 1947 and 1948, and was named by the Advisory Committee on Antarctic Names for Chief Construction Electrician John W. Drew, U.S. Navy, a member of the Wilkes Station party of 1958.
Midgley Island is a rocky island, 0.8 nautical miles (1.5 km) long, lying immediately south of Hollin Island in the Windmill Islands of Antarctica. It was first mapped from air photos taken by U.S. Navy Operation Highjump and Operation Windmill in 1947 and 1948. The island was named by the Advisory Committee on Antarctic Names for Lieutenant E.W. Midgley, an Army Medical Corps observer who assisted Operation Windmill parties in establishing astronomical control stations between Wilhelm II Coast and Budd Coast during the 1947–48 season.
The Løken Moraines are a line of north–south trending moraines, about 7 nautical miles (13 km) long, lying from 0.5 to 2 nautical miles inland from the Windmill Islands off Antarctica, just east of the bases of Clark, Bailey and Mitchell Peninsulas. The moraines were first mapped from air photos taken by U.S. Navy Operation Highjump (1946–47) and Operation Windmill (1947–48), and were named by Carl R. Eklund for Olav Løken, a Norwegian glaciologist who was a member of the Wilkes Station party, 1957.
Sparkes Bay is a bay, 1 nautical mile (1.9 km) wide and indenting 2.5 nautical miles (4.6 km) between Mitchell Peninsula on the north and Robinson Ridge and Odbert Island on the south, in the Windmill Islands. First mapped from air photos taken by U.S. Navy Operation Highjump and Operation Windmill in 1947 and 1948. Named by the Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant Robert S.
