Qaanaaq, one of the northernmost villages in Greenland, has winters where the sun does not appear for more than three months. The town is so remote that its six hundred or so residents remain virtually isolated from the rest of the country year-round. In the spring, when the ice thaws, some of the community's Inuit members begin to hunt narwhal, small whales with large, sharply pointed tusks which live only in the Arctic.
