The town's name comes from an Indian word meaning "warm wind," and it's this wind, melting the snow in January and February, that makes it possible for cattle to reach the rich bunchgrass and survive. While in town visit the Blaine County Museum featuring area history and artifacts. The Bear Paw Battlefield is the site of the last major Indian battle in the U.S. and is located just 16 miles south of Chinook. It is one of Montana's three units of the Nez Perce Historic Park.
