Above the Arctic Circle, in Canada's far north sits Auyuittuq National Park. This remote wilderness is home to polar bears, massive glaciers and Mount Thor-one of the sharpest sheer drops to be found on the planet. 'Auyuittuq' means 'The Land That Never Melts' in Inutituk, the language of the Inuit. However, research reports rising temperatures and this once frozen landscape is changing.
