An 11ft wooden Nansen-type sledge constructed from ash on a hickory wood frame. It is made up of six uprights and cross-members reinforced with leather straps and iron braces. Drag ropes are attached around the uprights at both ends of the sledge. At one end the runner has become detached from the frame.

The sledge was used on the British Antarctic 'Nimrod' Expedition led by Ernest Shackleton (1907-1909) and was part of the equipment taken by the Southern Party to reach the South Pole. The Southern Party reached within 97 miles of the Pole before turning back. The sledge was used as a depot marker on the outward journey at 'Grisi Depot' but reused on the return journey after the party's previous sledge fell apart. The sledge was retrieved and kept by Dr Eric Marshall, who had accompanied Shackleton to the South Pole. He then donated it to his old school Monkton Combe, Bath in the 1950s along with his sledge flag from the same expedition (now held at the Scott Polar Research Institute).
