"We literally had an hour before we were going to leave, when we started to find parts of their gear and remnants of their trip that was indisputably theirs," Post said of the expedition that took place in August.The team recovered a portion of Washburn's cherished aerial F-8 camera — a format he would later become known for worldwide — as well as two motion picture cameras and old climbing gear, tents and cooking items.Dora Medrzycka, a postdoctoral fellow at the University of Ottawa and the scientist who thought up the new theory, said the discovery all came down to how far the glacier had moved since Washburn's day.Post had been fascinated by Washburn's failed 1937 attempt to climb Mount Lucania — during which he abandoned the gear — ever since reading about it in a book."We projected it would have moved perhaps 10 kilometres down the glacier, but when they actually got to the field, it had really moved much further than that," he said."
