Gordon M. Haslop, RNZAF (1922-61), New Zealand second pilot of the RAF contingent of the CTAE in 1956-58.[5]
Mount Homard

First mapped in 1957 by the CTAE and named for Sgt. Major Desmond E.L. Homard, engineer with the advance party and transpolar party of the CTAE, 1955-58.[6]
Mount Pivot
80°41′S 30°10′W. Conspicuous mountain, 1,095 metres (3,593 ft), with steep rock slopes on its west side, standing between Mount Haslop and Turnpike Bluff in the west part of the Shackleton Range. First mapped in 1957 by the CTAE and so named because this prominent landmark was the turning point for aircraft and sledging parties of the expedition rounding the southwest end of the Shackleton Range.[7]
Trey Peaks
80°36′S 28°52′W. Three conspicuous rock peaks, the highest 1,180 metres (3,870 ft). They stand west of Blaiklock Glacier and 2 miles (3.2 km) north of Mount Homard in the west part of Shackleton Range. First mapped in 1957 by the CTAE and given this descriptive name, trey being a term for three used in dice or cards.[8]
Turnpike Bluff
80°44′S 30°04′W. Conspicuous rock bluff at the southwest extremity of the Shackleton Range, 5 miles (8.0 km) southwest of Mount Homard. First mapped in 1957 by the CTAE and so named because it marks the beginning of a badly crevassed area of Recovery Glacier through which the vehicles of the CTAE had difficulty in passing on their journey from Shackleton Base to the South Pole in 1957.[9]
Wyeth Heights
80°45′S 29°33′W. Rock heights rising to 1,335 metres (4,380 ft) at the head of Blaiklock Glacier, forming the southeast extremity of Otter Highlands in western Shackleton Range.
