The Branstetter Rocks ( 70°7′S72°40′E / 70.117°S 72.667°E / -70.117; 72.667 Coordinates: 70°7′S72°40′E / 70.117°S 72.667°E / -70.117; 72.667 ) are a small group of rocks lying 1 nautical mile (2 km) east-northeast of Thil Island in the eastern part of the Amery Ice Shelf. They were delineated in 1952 by John H. Roscoe from air photos taken by U.S. Navy Operation Highjump (1946–47), and named by him for J.C. Branstetter, an air crewman on Operation Highjump photographic flights in the area. [1]

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Thil Island is a small rocky island lying 1 nautical mile (1.9 km) northeast of Jennings Promontory in the eastern part of the Amery Ice Shelf. Delineated in 1952 by John H. Roscoe from air photos taken by U.S. Navy Operation Highjump, 1946-47. Named by Roscoe for R.B. Thil, air crewman on Operation Highjump photographic flights over this area.

Amery Ice Shelf ice shelf in Antarctica

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 February 11, 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.

The Grove Mountains are a large, scattered group of mountains and nunataks extending over an area of approximately 40 by 20 miles, located 100 miles (160 km) east of the Mawson Escarpment in American Highland, Antarctica. They were first photographed from the air by aircraft of U.S. Navy Operation Highjump, 1946–47, and named by the Antarctic Names Committee of Australia for Squadron Leader I.L.

Wilson, a zoologist with the expedition, who perished with Scott on the return journey from the South Pole.
