Clowes Glacier . A glacier wide, which flows east to enter Mason Inlet. Discovered and photographed from the air in December 1940 by the US AS. During 1947 it was photographed from the air by the RARE under Ronne, who in conjunction with the FIDS charted it from the ground. Named by the FIDS for Archibald J. Clowes.
Mason Inlet . Ice-filled inlet which recedes southwest between Cape Mackintosh and the coastline south of
Cape Herdman, along the east coast of Palmer Land. First seen and photographed from the air in December 1940 by members of the USAS. During 1947 the inlet was photographed from the air by the RARE, who in conjunction with the FIDS charted it from the ground. Named by the FIDS for D.P. Mason, their surveyor on the joint British-American sledge journey during the charting of this coast in 1947.
Cape Mackintosh . A low, ice-covered cape forming the north tip of Kemp Peninsula and the east entrance point to Mason Inlet. Probably first seen by members of the USAS who photographed a portion of Kemp Peninsula while exploring this coast from the air in December 1940. During 1947 the cape was photographed by the RARE, which in conjunction with the FIDS surveyed it from the ground. Named by the FIDS after Neil A. Mackintosh (1900–74), British marine biologist, oceanographer, and authority on Antarctic whales; member of DI scientific staff from 1924 and Chief Scientific Officer, 1929–49; Deputy Director, National Institute of Oceanography (now
Institute of Oceanographic Sciences), 1949-61.
Cape Deacon . An ice-covered cape forming the southeast tip of Kemp Peninsula. Probably first seen by members of the
United States Antarctic Service (USAS) who photographed a portion of Kemp Peninsula while exploring this coast from the air in December 1940. During 1947 the cape was photographed from the air by members of the RARE, who in conjunction with the FIDS charted it from the ground. Named by the
UK Antarctic Place-Names Committee (UK-APC) after George E.R. Deacon (1906–84), English oceanographer and member of the Discovery Investigations staff, 1927–39; Director of the National Institute of Oceanography, 1949-71.
Jeffries Bluff . The ice-covered south point of Kemp Peninsula on the Lassiter Coast. The feature was photographed from the air by the USAS in December 1940, surveyed by the joint RARE-FIDS sledge party in November 1947 and rephotographed by the
United States Navy, 1965-67. In association with Cape Deacon to the northeast, named by the UK-APC in 1981 after Margaret Elsa Jeffries (Mrs. George Deacon), a member of the staff of the
Discovery Committee, about 1930.
Mossman Inlet . Narrow ice-filled inlet which recedes north between
Cape Kidson and the southwest end of Kemp Peninsula. This inlet was first seen and photographed from the air in December 1940 by the USAS. During 1947 it was photographed from the air by the RARE under Ronne, who in conjunction with the FIDS charted it from the ground. Named by the FIDS for Robert C. Mossman, 1870-1940, British meteorologist and climatologist and member of the ScotNAE under Bruce, 1902-04.
Mount Pawson . A mountain southeast of Mohn Peaks. First mapped by the FIDS-RARE joint sledge party of 1947-48. Remapped by the
United States Geological Survey (USGS) from surveys and United States Navy air photos, 1961-67. Named by the United States
Advisory Committee on Antarctic Names (US-ACAN) for David L. Pawson, biologist with the Palmer Station-Eastwind Expedition, summer 1965-66.
Mohn Peaks . Two ice-covered peaks, the northern and southern high and high, respectively, standing west-southwest of the head of Mason Inlet. First seen and photographed from the air in December 1940 by the USAS. During 1947 the peaks were photographed from the air by the RARE under
Finn Ronne, who in conjunction with the FIDS charted them from the ground. Named by the FIDS for
Henrik Mohn. ==References==
