After 3 years of planning, Steve Hall takes viewers along with him as he backpacks through Akshayuk Pass in Canada's Auyuittuq National Park. The spectacular scenery on Baffin Island includes Mount Thor, which has the greatest vertical drop of any mountain in the world, and Mount Asgard, which has a unique cylindrical shape with a flat top. On his journey, Steve must deal with the weather, raging rivers, unstable moraines, and morale-draining wet bogs.
