Martin Peninsula

Martin Peninsula (74°20′S 114°30′W) is a peninsula about 60 nautical miles (110 km; 69 mi) long and 20 nautical miles (37 km; 23 mi) 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. Location The Martin Peninsula extends north from the coast of Marie Byrd Land into the Amundsen Sea. It defines the boundary between the Bakutis Coast to the west of Cape Herlacher, and the Walgreen Coast to the east. Glade Bay and Sweeny Inlet are on its west side, which is the eastern limit of the Getz Ice Shelf. The Dotson Ice Shelf extends east from its eastern side. The Kohler Range is to its south. The 1960 Sailing Directions for Antarctica described the peninsula as follows: Martin Peninsula projects about 70 miles northward from the mainland terminating in two smaller peninsulas formed by an inlet 15 miles long. Cape Harlacher is the northern extremity of the northwestern peninsula. From Cape Herlacher to Cape Flying Fish, about 190 miles westward, the coast is indented by a very large bay and a smaller bay, the two separated by an anvil-shaped peninsula 65 miles broad in its seaward front. The very large bay is formed between the western side of the Martin Peninsula and the eastern side of the anvil-shaped peninsula. Exploration and name The peninsula was 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 Col. Lawrence Martin, United States Army (Ret.), American geographer and authority on Antarctic exploration with the Library of Congress; member of US-SCAN, 1943–46.
