Even today, with advanced foods, and radios, and insulated clothing, a journey on foot across Antarctica is one of the harshest tests a human being can be asked to endure. A hundred years ago, it was worse. Australian explorer Douglas Mawson's journey has gone down in the annals of polar exploration as probably the most terrible ever undertaken in Antarctica.
Above is the last photo of Mawson's party, taken when they left the Australasian Antarctic base camp on November 10, 1912. By January 10, 1913, two of the three men would be dead, and expedition leader Douglas Mawson would find himself exhausted, ill and still more than 160 miles from the nearest human being.
