Quarles Range is a high and rugged range of the Queen Maud Mountains, extending from the polar plateau between Cooper Glacier and Bowman Glacier and terminating near the edge of Ross Ice Shelf.
The Airy Glacier is a glacier 20 nautical miles (37 km) long and 6 nautical miles (11 km) wide, flowing west to the northeast portion of Forster Ice Piedmont, near the west coast of the Antarctic Peninsula.
Coker Ice Rise is a small ice rise in Wordie Ice Shelf, 6 nautical miles (11 km) west-northwest of the Triune Peaks, Fallières Coast. It was photographed from the air by the Ronne Antarctic Research Expedition, 1947–48, and surveyed by the Falkland Islands Dependencies Survey, 1958. It was named by the Advisory Committee on Antarctic Names for Walter B. Coker, U.S. Navy, radioman, Palmer Station winter party, 1969.
Norman Peak is a peak rising to 1,790 m on the north side of Airy Glacier, 4 nautical miles (7 km) north-northeast of Anchor Crag and 3.8 nautical miles (7 km) west of Peregrinus Peak, in southwest Graham Land. The peak was photographed from the air by Ronne Antarctic Research Expedition (RARE), 1947, and was surveyed by Falkland Islands Dependencies Survey (FIDS), 1958. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) after Robert Norman, English compass maker who fortuitously discovered magnetic dip in 1576.
Wade Ice Rise is a small ice rise in Wordie Ice Shelf, 8 nautical miles (15 km) northwest of Triune Peaks, Fallières Coast. Photographed from the air by Ronne Antarctic Research Expedition (RARE), 1947–48, and surveyed by Falkland Islands Dependencies Survey (FIDS), 1958. Named in 1977 by Advisory Committee on Antarctic Names (US-ACAN) after George W. Wade, Jr., U.S. Navy, Chief Construction Electrician, Palmer Station, winter party 1970.
The Playfair Mountains are a group of mountains between Swann Glacier and Squires Glacier in southeast Palmer Land, Antarctica.
Paradise Harbour is a wide embayment behind Lemaire Island and Bryde Island, indenting the west coast of Graham Land, Antarctica, between Duthiers Point and Leniz Point. The name was first applied by whalers operating in the vicinity and was in use by 1920.
Flinders Peak is a conspicuous triangular peak, 960 metres (3,150 ft) high, on the west end of the Bristly Peaks. The peak overlooks Forster Ice Piedmont near the west coast of the Antarctic Peninsula. It was photographed from the air by the British Graham Land Expedition and the Ronne Antarctic Research Expedition. It was surveyed from the ground by the Falkland Islands Dependencies Survey in December 1958, and was named by the UK Antarctic Place-Names Committee after Matthew Flinders, an English navigator who discovered the cause of deviation in magnetic compasses, and pointed the way to a solution, 1805–14.
Hariot Glacier is a glacier flowing northwest along the south side of Morgan Upland before turning west into the northern portion of the Wordie Ice Shelf, along the west coast of the Antarctic Peninsula. It was roughly surveyed by the British Graham Land Expedition, 1936–37, and the upper reaches were photographed from the air by the Ronne Antarctic Research Expedition, 1947. The glacier was surveyed from the ground by members of the Falkland Islands Dependencies Survey who traveled along it in December 1958, and it was named by the UK Antarctic Place-Names Committee after Thomas Hariot, an English mathematician who pioneered new methods of navigation under the patronage of Sir Walter Raleigh.
Steinemann Island is an island off the northeast coast of Adelaide Island, about 10 nautical miles (18 km) southwest of Mount Velain. Mapped from air photos taken by Ronne Antarctic Research Expedition (RARE) (1947–48) and Falkland Islands and Dependencies Aerial Survey Expedition (FIDASE) (1956–57). Named by United Kingdom Antarctic Place-Names Committee (UK-APC) for Samuel Steinemann, Swiss physicist who has made laboratory investigations on the flow of single and polycrystalline ice.
Hotine Glacier is a glacier 10 nautical miles (19 km) long which is divided at its mouth by Mount Cloos, flowing west into both Deloncle Bay and Girard Bay on Kyiv Peninsula, on the west coast of Graham Land, Antarctica. It was first charted by the Belgian Antarctic Expedition under Gerlache, 1897–99, and was named by the UK Antarctic Place-Names Committee in 1959 for Brigadier Martin Hotine, Director of Overseas Surveys.
Lasher Spur is a prominent mountain spur trending northwest from the Kelvin Crests, 4 nautical miles (7 km) east-northeast of the Triune Peaks, Fallières Coast, Antarctica. The spur was photographed from the air by the Ronne Antarctic Research Expedition, 1947, and the U.S. Navy, 1966, and was surveyed by the Falkland Islands Dependencies Survey, 1958. It was named in 1977 by the Advisory Committee on Antarctic Names for Lieutenant William J. Lasher, U.S. Navy, an LC-130 aircraft commander in Operation Deep Freeze, 1969 and 1970.
