The 1000 metre west face of Mount Thor is a big wall classic for all enthusiasts. It is completely overhanging, with an average tilt of 105 degrees. The 800-metre west face of Mount Asgard also gives a formidable challenge to even the best climbers.
VI aid routes are established on both of the peak before mentioned, as well as many other peaks in the Auyuittug National Park. Many peaks in this park have been climbed in the past decade, but first ascents are being put up every year.
This is a harsh and remote climate, unlike that of Yosemite. This climate makes rescue near impossible, therefore you have to be an expert climber before you tackle one of these routes.
If you want to play with the big boys, come to Nunavut for some classic big walls and a lot of fun.
