Corell Cirque
Corell Cirque () is a large cirque, which is a concave amphitheater shaped valley containing a glacier. It is between Harvey Cirque and Duncan Bluff in the southern part of the Darwin Mountains. Located at the eastern end of the extensive Prebble Icefalls, the cirque channels some of the ice from the Midnight Plateau icecap into the Hatherton Glacier. It was named after Robert Corell, who headed the Geosciences Directorate at the National Science Foundation The National Science Foundation (NSF) is an independent agency of the United States government that supports fundamental research and education in all the non-medical fields of science and engineering. Its medical counterpart is the National I ..., 1987–99, which for many years included the Foundation's Polar Research, and who chaired national and international groups evaluating global change.

Cirque
A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the down ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between lati ...

Harvey Cirque
Harvey Cirque () is a cirque containing a small glacier between Scheuermann Spur and Corell Cirque in the southern part of the Darwin Mountains of Antarctica. The cirque occurs along the extensive Prebble Icefalls which contribute some ice to the head of the cirque; there is limited flow from the cirque to Hatherton Glacier. It was named after geologist Ralph P. Harvey of Case Western Reserve University, Cleveland, Ohio, who was engaged in the United States Antarctic Program The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the A ...

Duncan Bluff
Duncan Bluff () is a steep rock bluff along the north side of Hatherton Glacier. It rises to between Corell Cirque and Conant Valley in the Darwin Mountains. In association with the names of communication workers grouped in this area, it was named after Patrick Duncan Smith of the Office of Polar Programs, National Science Foundation, 1995–2001, an information technology specialist for the United States Antarctic Program The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the A ... with responsibility for projects that access communication satellites as well as for Antarctic communication with the outside world.

Midnight Plateau
Midnight Plateau () is a prominent ice-covered plateau, over high, forming the central feature of the Darwin Mountains in Antarctica. It is the only area of snow accumulation in the Darwin Mountains. The plateau was discovered by the Victoria University of Wellington Antarctic Expedition The Antarctic Research Centre (ARC) is part of the School of Geography, Environment and Earth Sciences at Victoria University of Wellington. Its mission is to research " Antarctic climate history and processes, and their influence on the global clim ... of 1962–63 and so named because the feature was visited by expedition members at midnight on December 27, 1962.

Hatherton Glacier
Hatherton Glacier is a large glacier flowing from the Antarctic polar plateau generally eastward along the south side of the Darwin Mountains and entering Darwin Glacier at Junction Spur. It was mapped by the Darwin Glacier Party of the Commonwealth Trans-Antarctic Expedition (1956–58), and was named for Trevor Hatherton, Scientific Officer in Charge of Antarctic Activities at the Department of Scientific and Industrial Research, Wellington, New Zealand.

National Science Foundation
The National Science Foundation (NSF) is an independent agency of the United States government that supports fundamental research and education in all the non-medical fields of science and engineering. Its medical counterpart is the National Institutes of Health. With an annual budget of about $8.3 billion (fiscal year 2020), the NSF funds approximately 25% of all federally supported basic research conducted by the United States' colleges and universities. In some fields, such as mathematics, computer science, economics, and the social sciences, the NSF is the major source of federal backing. The NSF's director and deputy director are appointed by the President of the United States and confirmed by the United States Senate, whereas the 24 president-appointed members of the National Science Board (NSB) do not require Senate confirmation. The director and deputy director are responsible for administration, planning, budgeting and day-to-day operations of the foundation, while t ...
