The Iditarod National Historic Trail is a network of 2,037 miles of trails once used by ancient Alaska Natives and early 20th- century prospectors. The vegetation varies from coastal Sitka spruce to the alpine tundra of the Chugach Mountains and Alaska Range. Wildlife is plentiful and includes moose, caribou, black bear, brown bear, lynx, beaver, otter, marten, bald eagle, and all types of waterfowl. Fish species include salmon, steelhead, Dolly Varden, trout, and arctic graying. The Iditarod received its Historic Trail designation from Congress in 1978 for its historic importance. The Trail is the route for the Iditarod Trail Sled Dog Race.
