In association with the names of pioneers of polar life and travel grouped in this area, it was named by the UK Antarctic Place-Names Committee in 1971 after Major Frederick George Jackson, an English Arctic explorer who in 1895 designed the features of the pyramid tent, later to become standard equipment on British polar expeditions.

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.

Nunatak Exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier

A nunatak is an exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons.

Pioneers Escarpment

Pioneers Escarpment is a mostly snow-covered north-facing escarpment, interrupted by occasional bluffs and spurs, between Slessor Glacier on the north and Shotton Snowfield on the south, in the Shackleton Range. The escarpment was photographed from the air by the U.S. Navy, 1967, and was surveyed by British Antarctic Survey (BAS), 1968-71. So named by United Kingdom Antarctic Place-Names Committee (UK-APC) because features on the escarpment are named after the pioneers whose inventions have assisted living and traveling conditions in the polar regions.
