They have a great sense of smell

Arctic foxes can smell carcasses left by polar bears up to 40 km away — not a bad skill to have in years when there are fewer lemmings running around. And speaking of lemmings — while Arctic foxes can hear lemmings several centimetres below the surface of the snow, they can smell them even farther down — up to 77 centimetres deep.
