Mawson's plan was to map the coastline of King George V Land, but instead it ended in a tragedy. On the 14 of January, Belgrave Edward Sutton Ninnis fell down a crevasse to his death, bring with him supplies, dogs and a tent. Then another disaster struck, when Swiss champion skier Xavier Mertz died of poisoning due to the scarce amount of food. Mawson and Mertz ate their huskey's livers, thinking it would be nutritious, it instead killed him. For more info see Mertz's death and Ninnis' death.
