Exploration and naming

edit

The seaward parts of the Mountaineer Range were first viewed by James Clark Ross in 1841, and subsequently by several British and later American expeditions. The precise mapping of its overall features was accomplished from United States Navy air photographs and surveys by New Zealand and American parties in the 1950s and 1960s. The range was named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1958–59, in keeping with the backgrounds of members of the 1957–58 and 1958–59 field parties who made a reconnaissance of the area, and also in association with the names "Aviator" and "Mariner".[1]

Location

edit

The Mountaineer Range lies to the south of the Victory Mountains and northeast of the Southern Cross Mountains. It is bounded by the Aviator Glacier which forms below the Half-ration Névé to the west, and flows south-southeast to Lady Newnes Bay. The bay forms the eastern boundary of the range. To the north it is bound by the Hercules Névé and Mariner Glacier, which flows southeast to Lady Newnes Bay.[2][3] Features of the eastern part include Bunker Bluff, Engberg Bluff, Index Point, Gauntlet Ridge, Spatulate Ridge, Apostrophe Island, Caliper Cove and Cape King.[3]

Fumaroles and geothermally heated ground occur within a single outcrop at the summit of Mount Rittmann in a minor caldera rim at approximately 2,000 metres (6,600 ft) above sea level. Mount Rittmann was identified as a volcano by the 4th Italian Antarctic Expedition in the 1988/89 field season, and named by them in 1991 for the volcanologist Alfred Rittmann (1893-1980).[6]
