Mount Thor, in Auyuittuq National Park on Baffin Island, Nunavut, Canada, presents a 4,100 foot pure vertical drop. Mt. Thor is Canada's most famous peak, and it's made of pure granite. It's a favorite of thrill seekers and climbers. Mount Thor was first climbed in 1953 by an Arctic Institute of North America team. There have been a few recent rappel expeditions, with one fatality in 2006.
