Possibly sighted by FAE, 1908-10, in January 1909; surveyed by British Antarctic Survey (BAS), 1975-76. Named after Alec Edward Simon, BAS aircraft mechanic, Adelaide, summers 1972-76.

Simon Ridge
Simon Ridge (-71.05°N, 65.5°W) is an arc-shaped rock ridge about 8 nautical miles (15 km) southeast of Husky Massif in the Prince Charles Mountains. Plotted from ANARE (Australian National Antarctic Research Expeditions) air photos taken in 1960. Named for M.J. Simon, radio officer at Wilkes Station in 1962.

Simoom Hill
Simoom Hill (-69.46667°N, -67.93333°W) is an one of the Relay Hills, rising to 640 m, 3 nautical miles (6 km) east of Mount Edgell in western Antarctic Peninsula. Named in 1977 by the United Kingdom Antarctic Place-Names Committee (UK-APC) in association with other wind names in the area. Simoom is the warm south wind that blows off the Arabian Desert.

Simplicity Hill
Simplicity Hill (-85.1°N, -174.63333°W) is a small ice-free hill rising 1 nautical mile (1.9 km) west of Crilly Hill, at the north side of McGregor Glacier, in the Queen Maud Mountains. So named by the Texas Tech Shackleton Glacier Expedition (1964-65) because of the ease with which they were able to approach the feature, and because of the relative simplicity of its geologic nature.

Simpson Bluff
Simpson Bluff (-72.45°N, -96.1°W) is a broad ice-covered bluff at the east end of Thurston Island. The bluff stands between Levko Glacier and Savage Glacier where they enter Seraph Bay. Named by Advisory Committee on Antarctic Names (US-ACAN) after Photographer's Mate R.M. Simpson, aircrewman in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas, 1946-47.

Simpson Crags
Simpson Crags (-74.4°N, 162.75°W) is a series of rugged crags descending southeast from Mount Baxter of the Eisenhower Range and forming the south wall of O'Kane Glacier, in Victoria Land. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1955-63. Named by Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant Commander William A. Simpson, Jr., U.S. Navy, aircraft commander with Squadron VX-6 during U.S. Navy Operation Deepfreeze 1967.

Simpson Glacier
Simpson Glacier (-71.28333°N, 168.63333°W) is a glacier, 6 nautical miles (11 km) long, in the Admiralty Mountains. It flows northward to the coast between Nelson Cliff and Mount Cherry-Garrard where it forms the Simpson Glacier Tongue. The latter feature was named by the British Antarctic Expedition, 1910-13, after Sir George Simpson, meteorologist of the expedition. The glacier described was mapped by United States Geological Survey (USGS), 1960-63, and was so named by Advisory Committee on Antarctic Names (US-ACAN) because (with Fendley Glacier to the east) it nourishes the Simpson Glacier Tongue.

Simpson Glacier Tongue
Simpson Glacier Tongue (-71.25°N, 168.75°W) is a small floating glacier tongue nourished by Simpson Glacier and Fendley Glacier as it extends into the sea between Nelson Cliff and Atkinson Cliffs, along the north coast of Victoria Land. Charted by the Northern Party, led by Campbell, of the British Antarctic Expedition, 1910-13. Named for Dr. (later Sir) George C. Simpson, meteorologist of the expedition.

Simpson Head
Simpson Head (-73.35°N, -60.98333°W) is a conspicuous promontory rising to 1,065 meters. It projects south into the north side of New Bedford Inlet 4 nautical miles (7 km) northwest of Cape Kidson, on the east coast of Palmer Land. Discovered and photographed from the air in December 1940 by members of the United States Antarctic Service (USAS). During 1947 it was photographed from the air by members of the Ronne Antarctic Research Expedition (RARE), who in conjunction with the Falkland Islands Dependencies Survey (FIDS) charted it from the ground. Named by the FIDS for Sir George C. Simpson.
