Reinbolt Hills
Reinbolt Hills () is a group of rocky hills, low to moderate in height and about 5 nautical miles (9 km) long, situated 9 nautical miles (17 km) east of Gillock Island at the eastern margin of the Amery Ice Shelf. Delineated in 1952 by John H. Roscoe from air photos taken by U.S. Navy Operation Highjump (1946–47), and named by him for Lieutenant Fred L. Reinbolt, U.S. Navy, co-pilot on Operation Highjump Operation HIGHJUMP, officially titled The United States Navy Antarctic Developments Program, 1946–1947, (also called Task Force 68), was a United States Navy (USN) operation to establish the Antarctic research base Little America IV.

Gillock Island
Gillock Island is an ice-covered island, long and wide, with numerous rock outcrops exposed along its flanks. It is aligned north–south and lies in the eastern part of Amery Ice Shelf. Delineated in 1952 by John H. Roscoe from air photos taken by U.S. Navy Operation Highjump (1946–47). Named by him for Lieutenant Robert A. Gillock, U.S. Navy, navigator on Operation Highjump photographic flights over this and other coastal areas between 14°E and 164°E. The Bain Crags () are a number of rock exposures, many of which are banded, in the face of or projecting from the ice cliffs along the south part of the west side of Gillock Island. The feature was visited in January 1969 by J.H.C. Bain, geologist with the Australian National Antarctic Research Expeditions Prince Charles Mountains survey party, after whom it is named.

Amery Ice Shelf
The Amery Ice Shelf () is a broad ice shelf in Antarctica at the head of Prydz Bay between the Lars Christensen Coast and Ingrid Christensen Coast. It is part of Mac. Robertson Land. The name "Cape Amery" was applied to a coastal angle mapped on 11 February 1931 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Douglas Mawson. He named it for William Bankes Amery, a civil servant who represented the United Kingdom government in Australia (1925–28). The Advisory Committee on Antarctic Names interpreted this feature to be a portion of an ice shelf and, in 1947, applied the name Amery to the whole shelf. In 2001 two holes were drilled through the ice shelf by scientists from the Australian Antarctic Division and specially designed seabed sampling and photographic equipment was lowered to the underlying seabed. By studying the fossil composition of sediment samples recovered, scientists have inferred that a major retreat of the Amery Ice Shelf to ...

Operation Highjump
Operation HIGHJUMP, officially titled The United States Navy Antarctic Developments Program, 1946–1947, (also called Task Force 68), was a United States Navy (USN) operation to establish the Antarctic research base Little America IV. The operation was 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. HIGHJUMP's objectives, according to the U.S. Navy report of the operation, were: # Training personnel and testing equipment in frigid conditions; # Consolidating and extending the United States' sovereignty over the largest practicable area of the Antarctic continent (publicly denied as a goal before the expedition ended); # Determining the feasibility of establishing, maintaining, and utilizing bases in the Antarctic an ...

Hills Of Mac
A hill is a landform that extends above the surrounding terrain. It often has a distinct summit. Terminology The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as steep as a mountain. Geographers historically regarded mountains as hills greater than above sea level, which formed the basis of the plot of the 1995 film ''The Englishman who Went up a Hill but Came down a Mountain''. In contrast, hillwalkers have tended to regard mountains as peaks above sea level. The ''Oxford English Dictionary'' also suggests a limit of and Whittow states "Some authorities regard eminences above as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least high, while the official UK government's definition of a mountain is a summit of or higher. Some definitions include a topographical prominence requirement, typically or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
