Douglas Mawson

A century ago, Australian explorer Douglas Mawson stared death in the face. Kneeling on the edge of a deep crevasse, he looked down in horror at the wreckage of the sledge that held most of his food and other vital supplies.
There was no sign of the companion who had also fallen into the icy embrace of the glacier.
Nearly 500km of blizzard swept terrain separated Mawson and his one surviving companion from the safety of their hut.
With the limited food on their other sledge, it was doubtful whether one, let alone both of them, could make it back alive.
Before this accident happened, Mawson had abandoned one of the sledges and rearranged the supplies and equipment on the remaining two. Not a good decision.
Rather than dividing the human and dog food equally between the two sledges, Mawson put all the dog food and most of the human food on the second sledge, while the first carried all the fuel and the cooker.
