Biscuit Step
Biscuit Step () is a step-like rise in the level of Tucker Glacier above its junction with Trafalgar Glacier, in Victoria Land. It is very crevassed in its north half, but there is a good route of easy gradient through it toward its southern end. Biscuits were an important part of the expedition's rations (Australasian colloquialism "tucker"), and a small cache of them was left near the step for the return down the glacier by the New Zealand Geological Survey Antarctic Expedition, 1957–58, which named the feature.
