The Caribou Inuit live in the District of Keewatin, in the communities of Chesterfield Inlet, Baker Lake, Rankin Inlet, Whale Cove, and Arviat. The landscape varies from lowlands and mudflats in the southeast to hilly, rocky terrain in the north. Large lakes, shallow tundra ponds and rivers dominate the landscape. The treeline is about 120km west of Arviat, the most southern community. As their name suggests, this community hunts mostly caribou, which provide materials for their food, clothing, shelter, and tools. The area is home to caribou, arctic hare, arctic ground squirrel, arctic fox, wolf, ptarmigan and geese. The inland waterways support fish like arctic char and lake trout while the marine waters sustain seals, beluga whales, walrus and polar bears.
