Council Grove State Park in western Montana, about eight miles northwest of Missoula along the Clark Fork River, is a small history-focused park with deep significance. Known in Salish as Člmé and also as Ncx̣͏ʷotew̓s, it is the site where the Hellgate Treaty was signed on July 16, 1855, by representatives of the United States government and the Bitterroot Salish, Pend d’Oreille, and Kootenai, creating the Flathead Indian Reservation. Covering 187 acres, the park’s old-growth ponderosa pines, grassy fields, and riverside cottonwoods preserve a landscape tied to that event, while the area also serves today for recreation such as hiking and fishing.
