Duffy Peak

Last updated

Duffy Peak ( 71°45′S70°40′W / 71.750°S 70.667°W / -71.750; -70.667 Coordinates: 71°45′S70°40′W / 71.750°S 70.667°W / -71.750; -70.667 ) is a peak southeast of Hageman Peak in the Staccato Peaks, southwest Alexander Island, Antarctica. Dargomyzhsky glacier extends and flows west from the base of Duffy Peak and enters the nearby Bach Ice Shelf. The peak was photographed from the air by Lincoln Ellsworth in 1935, and was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Joseph A. Duffy, a U.S. Navy aircraft pilot in Squadron VXE-6 during Operation Deep Freeze, 1969 and 1970. [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.

Hageman Peak is a montane landform pinnacle rising to about 940 metres (3,100 ft) at the northwest end of the Staccato Peaks in southern Alexander Island, Antarctica. The peak was photographed from the air by Lincoln Ellsworth in 1935, and was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Roger H. Hageman, U.S. Navy, an LC-130 aircraft commander during Operation Deep Freeze, 1969.

Staccato Peaks

Staccato Peaks is a series of rock peaks extending 11 miles (18 km) in a north-south direction, rising to about 940 m with Hageman Peak being the highest peak of the Staccato Peaks, rising from the snowfields 20 miles (32 km) south of the Walton Mountains in the south part of Alexander Island, Antarctica. The peaks were first sighted from the air by Lincoln Ellsworth on November 23, 1935, and mapped from photos taken on that flight by W.L.G. Joerg. Remapped from air photos taken by the Ronne Antarctic Research Expedition in 1947–48, by Searle of the Falkland Islands Dependencies Survey in 1960. The name, given by the United Kingdom Antarctic Place-Names Committee, refers to the precipitous and abrupt way in which the peaks rise from the surrounding snowfields and is associated with other musical names in the vicinity.
