In 1954 Warren T. Lee found the horn core of a bison associated with a hearth and four tools on the east bank of the Columbia River, at Quilomene Rapids, in western Grant County, Washington. The site was found when overflow from a reservoir in the Quincy scablands cut a channel through the floodplain terrace. The hearth and associated materials were located in the wall of the channel 4 feet beneath the surface of the terrace. The finds are important because they provide another association of bison with man in the Plateau which is probably equivalent in time to the little-known Cayuse I phase.
