Mount Thor Rock Climbing

Mount Thor, officially gazetted as Thor Peak, is a mountain with an elevation of 1,675 m (5,495 ft) located in Auyuittuq National Park, on Baffin Island, Nunavut, Canada. The mountain is located 46 km (29 mi) northeast of Pangnirtung and features the Earth's greatest purely vertical drop at 1,250 m (4,101 ft), with an average angle of 105 degrees. This feature makes the site popular with climbers, despite its remoteness. Camping is allowed, with the only official site being at the entrance to the Akshayuk Valley near Overlord Peak.

Mount Thor is part of the Baffin Mountains which in turn form part of the Arctic Cordillera mountain range. The mountain is made of granite and is the most famous of Canada's mountains named "Thor".

Donald Morton and Lyman Spitzer made the first ascent of Mount Thor in 1965 during the Alpine Club of Canada expedition led by Pat Baird. Pat Baird also led the 1953 geophysical expedition during which Hans Weber, J. Rothlisberger and F. Schwarzenbach climbed the North Tower of Mount Asgard for the first time.

The world record for longest rappel was set on Mount Thor, July 23, 2006, by an American team consisting of: Chuck Constable, Dirk Siron, Ben Holley, Kenneth Waite, Gordon Rosser, Donny Opperman, Deldon Barfuss, and Tim Hudson. A 26-year-old Canadian national park warden, Philip Robinson, also rappelled, but had a problem with his equipment and died when he dropped to the base of the mountain. There had been a previous attempt in 2004, but they returned without rappelling due to dangerous weather conditions.
