The Sno-Cat Tractor
The sno-cat tractor, named Able, was used by Vivian Fuchs, the leader of the Commonwealth Trans Antarctic Expedition in 1957. The expedition had their hearts set on making the first overland crossing of the Antarctic Continent and as this photo proves, their efforts paid off thanks to this tractor. But judging from that massive crevice separating the two landmasses, it’s obvious that it was extremely risky and could have easily had a tragic ending for both the tractor and the expedition.
