The Ronne Antarctic Research Expedition (RARE) was an expedition from 1947–1948 which researched the area surrounding the head of the Weddell Sea in Antarctica.
Finn Ronne led the RARE which was the final privately sponsored expedition from the United States and explored and mapped the last unknown coastline on earth and determined that the Weddell Sea and the Ross Sea were not connected. The expedition included Isaac Schlossbach, as second in command, who was to have Cape Schlossbach named after him. The expedition, based out of Stonington Island was the first to take women to over-winter. Ronne's wife, Edith Ronne was correspondent for the North American Newspaper Alliance for expedition and the chief pilot Darlington took his wife.
The Filchner-Ronne Ice Shelf, also known as Ronne-Filchner Ice Shelf, is an Antarctic ice shelf bordering the Weddell Sea.
Operation HIGHJUMP, officially titled The United States Navy Antarctic Developments Program, 1946–1947, was a United States Navy operation organized by Rear Admiral Richard E. Byrd, Jr., USN (Ret), Officer in Charge, Task Force 68, and led by Rear Admiral Ethan Erik Larson, USN, Commanding Officer, Task Force 68. Operation HIGHJUMP commenced 26 August 1946 and ended in late February 1947. Task Force 68 included 4,700 men, 13 ships, and 33 aircraft. Operation HIGHJUMP's primary mission was to establish the Antarctic research base Little America IV.
The Pensacola Mountains are a large group of mountain ranges of the Transantarctic Mountains System, located in the Queen Elizabeth Land region of Antarctica.
The Britannia Range is an Antarctic mountain range bounded by the Hatherton and Darwin glaciers on the north and the Byrd Glacier on the south, westward of the Ross Ice Shelf. Discovered by the British National Antarctic Expedition (1901–04) under Scott.
The Merrick Mountains. are a cluster of mountains, 13 km long, standing 11 km northeast of the Behrendt Mountains in Palmer Land, Antarctica. Discovered and photographed from the air by the Ronne Antarctic Research Expedition, 1947–1948, under Finn Ronne.
The Scaife Mountains is a group of mountains rising west of Prehn Peninsula and between the Ketchum and Ueda glaciers, in Palmer Land, at the base of Antarctic Peninsula.
Orville Coast is that portion of the coast of Antarctica lying west of Ronne Ice Shelf between Cape Adams and Cape Zumberge. It was discovered by the Ronne Antarctic Research Expedition (RARE), 1947–48, under Ronne, who named this coast for Captain Howard T. Orville, USN, Head of the Naval Aerological Service, who was largely responsible for formulating the RARE meteorological program. The name "Orville Coast" is considered a more useful reference than "Orville Escarpment," the name originally applied for this area.
Ketchum Glacier is an eastward flowing glacier at the base of Palmer Land, Antarctica, about 50 nautical miles (90 km) long, descending between the Latady Mountains and the Scaife Mountains into Gardner Inlet. It was discovered by the Ronne Antarctic Research Expedition (RARE), 1947–48, under Finn Ronne, who named it for Commander Gerald Ketchum, U.S. Navy, commander of the icebreaker USS Burton Island (AG-88) which broke the ice to free the RARE from Marguerite Bay for the return home.
Wetmore Glacier is a glacier about 40 miles (64 km) long, flowing southeast between the Rare Range and Latady Mountains into the north part of Gardner Inlet. It was discovered by the Ronne Antarctic Research Expedition (RARE), 1947–48, under Ronne, who named this feature for Alexander Wetmore, Secretary of the Smithsonian Institution, who assisted Ronne in laying out the scientific research program of the expedition.
Irvine Glacier is a glacier, 40 miles (64 km) long, draining southeast between the Guettard Range and the Rare Range into the northern part of Gardner Inlet, Antarctica. It was discovered by the Ronne Antarctic Research Expedition (RARE), 1947–48, under Finn Ronne, who named it for George J. Irvine, of the Engineer Depot at Fort Belvoir, Virginia, who outlined the RARE photographic program.
Quilty Nunataks is a group of nunataks which extend over 8 miles (13 km), located 15 miles (24 km) southwest of the Thomas Mountains in Palmer Land. Discovered by the Ronne Antarctic Research Expedition (RARE), 1947–48, led by Ronne, they were named by Advisory Committee on Antarctic Names (US-ACAN) for Patrick Quilty, geologist with the University of Wisconsin–Madison survey party to this area, 1965–66.
Isaac "Ike" Schlossbach was an American polar explorer, submariner and aviation pioneer.
Thuronyi Bluff is a prominent escarpment on the east coast of the Antarctic Peninsula, which faces the Larsen Ice Shelf and the Weddell Sea and lies immediately south of the Antarctic Circle. It is located above Mill Inlet in British Antarctic Territory at the base of the Cole Peninsula, between Balch Glacier and Gould Glacier; it is part of Graham Land. The bluff was first observed in aerial photographs taken on December 22, 1947, during the Ronne Antarctic Research Expedition. A modern satellite photo of Thuronyi Bluff and its adjoining glaciers can be seen here.
The Haag Nunataks in Antarctica are a group of three low elevations aligned nearly north-south. The dominant central nunatak and the southern elevation have definite rock exposures; the minor northern elevation may be entirely snow-covered. The feature was discovered by the Ronne Antarctic Research Expedition (1947–48), led by Finn Ronne, who named it "Mount Haag" for Joseph Haag, head of Todd Shipyards, New York City, which worked on the expedition ship. Aerial photographs obtained by U.S. Navy Squadron VX-6 in 1966 show the feature to be a group of nunataks, not a mountain, and the name was amended accordingly by the Advisory Committee on Antarctic Names.
The Latady Mountains are a group of mountains rising west of Gardner Inlet, Orville Coast, between Wetmore Glacier and Ketchum Glacier, in southeastern Palmer Land, Antarctica. They rise to about 1,700 metres (5,600 ft) and include from north to south Mount Aaron, McLaughlin Peak, Mount Robertson, Crain Ridge, Mount Wood, Mount Hyatt, Mount Terrazas and Schmitt Mesa.
The Guettard Range is a mountain range, 40 nautical miles (74 km) long and 10 nautical miles (19 km) wide, located northwest of Bowman Peninsula and between Johnston Glacier and Irvine Glacier, in the southeastern extremity of Palmer Land, Antarctica. The feature was photographed from the air by the Ronne Antarctic Research Expedition, 1947–48. It was mapped from United States Geological Survey surveys and U.S. Navy air photos, 1961–67, and was named by the Advisory Committee on Antarctic Names for French naturalist and geologist Jean-Étienne Guettard.
The Littlewood Nunataks are a group of four lichen-covered nunataks, rising to about 250 metres (800 ft) between Schweitzer Glacier and Lerchenfeld Glacier, on the Luitpold Coast of Antarctica. The nunataks are brick red in color. They were discovered and first roughly charted by the Second German Antarctic Expedition, 1911–12, under Wilhelm Filchner. They were visited by helicopter from the icebreaker USS Edisto on January 28, 1959, by John C. Behrendt of the United States Geological Survey, and Lieutenant Erickson, U.S. Navy, and were named by Behrendt after oceanographer William H. Littlewood of the U.S. Navy Hydrographic Office, who worked in this and adjacent parts of the Weddell Sea area during Operation Deep Freeze 1957 and 1959.
Meinardus Glacier is an extensive glacier in Palmer Land, Antarctica. It flows in an east-northeast direction to a point immediately east of Mount Barkow, where it is joined from the northwest by Haines Glacier, and then flows east to enter New Bedford Inlet close west of Court Nunatak, on the east coast of Palmer Land. The glacier was discovered and photographed from the air in December 1940 by the United States Antarctic Service. During 1947 it was photographed from the air by the Ronne Antarctic Research Expedition under Finn Ronne, who in conjunction with the Falkland Islands Dependencies Survey (FIDS) charted it from the ground. It was named by the FIDS for Wilhelm Meinardus, a German meteorologist and climatologist and author of many publications including the meteorological results of the German Antarctic Expedition under Drygalski, 1901–03.
Mount Horne is, at 1,165 metres (3,820 ft), the highest and most prominent mountain in the Quilty Nunataks, standing 12 nautical miles (22 km) east-northeast of Mount Hassage in Palmer Land, Antarctica. It was discovered by the Ronne Antarctic Research Expedition, 1947–48, under Finn Ronne, who named it for Bernard Horne of Pittsburgh, who furnished wind-proofs and other clothing for the expedition.
Rare Range is a rugged mountain range between the Wetmore and Irvine Glaciers, in Palmer Land. Discovered and photographed from the air by the Ronne Antarctic Research Expedition, 1947–48. Named by Advisory Committee on Antarctic Names (US-ACAN) in recognition of the contributions made by this expedition to knowledge of Palmer Land and the Antarctic Peninsula area.
