The goal of this paper is to demonstrate the ability to create a viable site location model of pre-historic archaeological sites in the Columbia Plateau Region that are older than 15,000 BP. The site location model is created by analyzing several different variables: previously discovered archaeological sites in the Columbia Plateau Region older than 10,000 BP, Missoula Flood modeling, Bonneville Flood geological evidence, and prehistoric climate data. The prehistoric site locations are used to...
