Whistle Pass is adjacent to the northeastern part of the heights. The heights were so named by the UK Antarctic Place-Names Committee in 1977 in association with Whistle Pass. [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.

Sullivan Glacier is a glacier flowing west into Gilbert Glacier, immediately south of Elgar Uplands in the north part of Alexander Island, Antarctica. The glacier was first sighted from a distance by the British Graham Land Expedition during a flight in 1937 and roughly mapped. Remapped from air photos taken by the Ronne Antarctic Research Expedition in 1947–48, by Searle of the Falkland Islands Dependencies Survey in 1960. In association with the names of other composers in this area, named by United Kingdom Antarctic Place-Names Committee after Sir Arthur Sullivan (1842–1900), English composer.

Mikado Glacier is a glacier on the north side of Mahler Spur, flowing west-northwest into Sullivan Glacier near the junction with Gilbert Glacier in northern Alexander Island, Antarctica. The glacier was so named by the UK Antarctic Place-Names Committee in 1977 in association with nearby Gilbert Glacier and Sullivan Glacier, after the operetta The Mikado.
