Wishram's location results from two major geological features: the location of the Celilo Falls on the Columbia River, and the access to the Central Oregon Plateau via the Deschutes River just across the falls from Wishram. The falls not only provided early peoples a reliable source of food, but it later provided a convenient location for an easily constructed railroad bridge crossing the Columbia. The Deschutes valley just to the south of the falls provided a route for rail access to the south, and ultimately to California.
