Nez Perce people
From the Nez Perce National Historical Park: Camas Prairie is interpreted at a highway pullout on the north side of U.S. Highway 95, about six miles (10 km) south of Grangeville. This large prairie was a Nez Perce gathering place, where camas roots were harvested for thousands of years. Several nontreaty bands gathered at Tolo Lake in early June 1877 in anticipation of moving to the Nez Perce reservation. In response to the forced move and other hostile actions, several young Nez Perce people took actions that precipitated the Nez Perce War.
