done in previous expeditions. A few members of the expedition spent the winter of 1927-1928 at the Walden farm training and testing trail gear. During the expedition, Walden and his 13 dogs moved thousands of pounds of supplies from the ship over the 16 mile trail to base camp. Chinook, the first dog of his breed, disappeared (presumably dying) on January 17, 1929 while moving supplies to base camp. Walden received the Congressional Medal for his efforts during the Antarctic Expedition in 1931. Death Walden died on March 26, 1947, while saving his wife from a fire in the kitchen of their farmhouse.
