Ferocious winds and blizzards severely limited exploratory trips made by leader Douglas Mawson and the men camped at Cape Denison on the Australasian Antarctic Expedition. It was nearly 10 months before they were able to set out on their planned sledding trips. This photo was taken while official photographer Frank Hurley was on the southern party, which worked its way toward the southern magnetic pole. The pole seen on their sled in the background acted as a mast for a sail that, when the weather allowed, helped move the sled over the ice.
