part of Shackleton Range (q.v.) between Slessor Glacier to the N, and Shotton Snowfield and Read Mountains to the S, extending from Jackson Tooth to Lundström Knoll, Coats Land, and continuing to the E-most nunataks of the range in the vicinity of Skiltvakta and Vindberget, Dronning Maud Land. Following air photography by USN in 1967 and ground survey by BAS from Halley, 1968-71, the escarpment was named after pioneers whose inventions have assisted living and travelling conditions in the polar regions, but the name was restricted to the part within Coats Land (APC, 1974, p.5). The name, with its Norwegian equivalent Pionerhallet, was later redefined to include the whole escarpment (BAS 250P sheet SU 26-30/1, 1-DOS 1978; APC, 1980, p.5).

A mostly snow-covered north-facing escarpment, interrupted by occasional bluffs and spurs, between Slessor Glacier on the N and Shotton Snowfield on the S, in the Shackleton Range. The escarpment was photographed from the air by the U.S. Navy, 1967, and was surveyed by BAS, 1968-71. So named by UK-APC because features on the escarpment are named after the pioneers whose inventions have assisted living and traveling conditions in the polar regions.
