Weippe Prairie is a "beautiful upland prairie field of about two by three miles bordered by farmland made from cleared pine forests" at 3,000 feet elevation in Clearwater County, Idaho, at Weippe, Idaho. Camas flowers grow well there, and attracted native gatherers of the camas roots. It is the location in Idaho where the Lewis and Clark Expedition emerged from crossing the Bitterroot Mountains on the Lolo Trail and first met the Nez Perce tribe of Native Americans.
