Shackleton Range

The Shackleton Range is a mountain range in Antarctica. Rising at Holmes Summit to 1,875 metres (6,152 ft), it extends in an east–west direction for about 160 kilometres (99 mi) between the Slessor and Recovery glaciers.[1]

Location in Antarctica

The range was named after Sir Ernest Shackleton, leader of the British Imperial Trans-Antarctic Expedition (or "Shackleton's Expedition") of 1914–16.[1]

Surveys

The Commonwealth Trans-Antarctic Expedition (CTAE), which in 1956 saw the range from the air, conducted a ground-level survey of its western part in 1957. The United States Navy photographed the range from the air in 1967. In 1968–69 and 1969–70, the British Antarctic Survey (based at Halley Station) conducted further ground surveys with support from US Navy C-130 Hercules aircraft.[1]

Geology

The Haskard Group and Turnpike Bluff Group rest unconformably on the Archean-Middle Proterozoic Shackleton Range Metamorphic Complex. The Ordovician-Early Devonian Blaiklock Glacier Group (475 Ma) also unconformably overlies the Shackleton Range Metamorphic Complex. This group is composed of sandstones and conglomerates, and is unconformably overlain by the Beacon Supergroup.[2]
