British Antarctic Expedition 1907 / Route and Surveys of the South Magnetic Polar Party 1908-09. From Triangulation and Traverses by Douglas Mawson B.Sc., B.E.

Rare, early c.20th map showing the route taken by the South Magnetic Pole Party in Shackleton’s British Antarctic Expedition published by the Royal Geographical Society.

This map records the route and scientific surveys undertaken by the South Magnetic Polar Party, a key component of the British Antarctic Expedition of 1907–1909, also known as the Nimrod Expedition, led by Ernest Shackleton.

The Nimrod Expedition of 1907–1909, was the first of three expeditions to the Antarctic led by Ernest Shackleton and his second time to the Continent. Its main target, among a range of geographical and scientific objectives, was to be first to reach the South Pole. This was not attained, but the expedition’s southern march reached a Farthest South latitude of 88° 23′ S, just 97.5 nautical miles (180.6 km; 112.2 mi) from the pole. This was by far the longest southern polar journey to that date.
