Name

edit

The Apocalypse Peaks were so named by the Victoria University of Wellington Antarctic Expedition (1958–59) because the peaks are cut by talus slopes which gives them the appearance of the "Riders of the Apocalypse."[1]

Location

edit
 
Insel Range north of center of mapped region

The Apocalypse Peaks are bounded by the Barwick Valley to the northeast and the Balham Valley to the southeast. The Willett Range lies to the west, the Cruzen Range (formerly part of the Clare Range) to the north, the Insel Range to the southeast and the Olympus Range to the south.[2]

Southern features

edit

Features of the south of the peaks include, from west to east,

Edbrooke Hill

The hill rises 100 metres (330 ft) high above the adjacent plateau ice, which diverges at the hill to the east-northeast-flowing Haselton Glacier and the east-flowing Huka Kapo Glacier. Named by New Zealand Geographic Board (NZGB) (2005) after Steven Edbrooke, geologist, New Zealand Geological Survey, who mapped coal measures at Mount Fleming, Shapeless Mountain, and Mount Electra in 1982-83; in upper Wright Valley, Clare Range, and Willett Range, 1992-93.[3]

It flows east, southward of Edbrooke Hill, and terminates nearly midway along the south side of Apocalypse Peaks. “Huka Kapo” is a Maori word, meaning driving hail, and was applied descriptively to this glacier by the New Zealand Geographic Board in 2005.[4]

Named by the New Zealand Geographic Board (2005) after John Bryan, an Australian coal geologist who led a party in mapping the Permian coal measures at Mount Fleming, Shapeless Mountain, and Mount Electra during one visit in 1982-83.[5]

The feature stands between the head of Albert Valley and Papitashvili Valley. Named by the New Zealand Geographic Board (2005) after Geoffrey (Toby) Rose, leader of a party that investigated coal measures in the Mount Bastion and Sponsors Peak area, 1984-85.[6]

77°23′26″S 161°01′19″E / 77.39048°S 161.021851°E / -77.39048; 161.021851. A peak rising to 1,600 metres (5,200 ft) high at the head of Hernandez Valley. Named by the New Zealand Geographic Board (NZGB) (2005) after Ian Turnbull, an Institute of Geology and Nuclear Sciences geologist, who was a member of geology mapping parties at Asgard Range, Victoria Valley, Saint Johns Range, and at the Mackay Glacier and Wilson Piedmont Glacier areas in several field seasons 1988-89 to 1997-98.[8]
