This park marks the site of the 1855 council between Isaac Stevens and the Flathead, Kootenai, and Pend d'Oreille Indians. Here the Indians signed the Hellgate Treaty and relinquished their ancestral hunting grounds in exchange for a reservation in the Mission Valley. There are 186.9 acres making up this site that sits at an elevation of 3,198 feet. This day use only site offers grills/firerings, vault toilets, picnic tables, drinking water, hiking trails, and disables accessible facilities. The park is designated ?Primitive? so there are no fees to enter and it is a pack-in/pack-out site. Golf courses and museums are both available nearby in Missoula. Vehicle size is limited to passenger cars.
