Mount Thor

Mount Thor, officially Thor Peak, rises in Auyuittuq National Park on Baffin Island, Nunavut, within the Baffin Mountains of the Arctic Cordillera. Known in Inuktitut as Qaisualuk and Kigutinnguaq, it is renowned for a 1,200-metre west-facing cliff above Akshayuk Pass, often cited as Earth’s greatest vertical drop and a major draw for climbers. Formed of ancient metamorphosed granite ranging from about 570 million to 3.5 billion years old, the mountain was dramatically shaped by glacial erosion. Its recorded climbing history includes the first ascent in 1965 and landmark ascents of the west face, solo routes, and the Southwest Buttress through 2012.
