Named after the Nordic god of Thunder, Mount Thor is the world’s tallest vertical rockface, which also makes it one of the most difficult rock formations to climb.
A part of the Auyuittuq National Park, on northern Canada’s remote Baffin Island, Mount Thor isn’t the park’s tallest peak, but it is definitely the most intimidating, especially when viewed from the west. It’s a 4,101-foot rock face, which makes it the longest vertical drop on the planet. But really, Mount Thor is steeper than vertical, as it is 105 degrees, making it more of an overhang. Many have tried scaling this monster overt he years, but dozens of rock climbers failed, until an American finally reached the summit in 1985, at the end of a grueling 33-day climb.
