Lofgren Peninsula (72°12′S 96°4′W / 72.200°S 96.067°W / -72.200; -96.067) is an ice-covered peninsula about 22 nautical miles (40 km) long, projecting between Cadwalader Inlet and Morgan Inlet on the northeast side of Thurston Island, Antarctica. The northern extremity of the peninsula is Cape Menzel, a bold rock cape. These features were discovered in helicopter flights from the USS Burton Island and the USS Glacier of the U.S. Navy Bellingshausen Sea Expedition in February 1960, and were named by the Advisory Committee on Antarctic Names (US-ACAN). The peninsula was named for Charles E. Lofgren, personnel officer with the Byrd Antarctic Expedition, 1928–30.^[1] The cape was named for Reinhard W. Menzel, a geomagnetist-seismologist with the Eights Station winter party, 1965.^[2]

Named features

Walsh Knob is a small but distinctive ice-covered elevation that rises midway along the south side of the peninsula. It has a rounded appearance except for a cliff at the south side. It was named by the US-ACAN after R.W. Walsh, Photographer's Mate in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas, 1946–47.^[3]

Mills Cliff is an isolated rock cliff in the north-central part of the peninsula. It was named by US-ACAN after Aviation Machinist's Mate William H. Mills, an aircrewman in the Eastern Group of Operation Highjump.^[4]
