The geology of the area is what brought people to the area shortly after the ice age.
At the end of the last ice age the Kettle Falls on the Columbia were exposed. “The Columbia in its natural state had the richest migratory fish resource in the world. It was becoming so, more than 9,000 years ago, and it remained so until the nineteenth century” (David Chance, People of the Falls).
Much of the 9,000 years is documented only by archaeologists, geologists and more recently by the oral history of the native people. The written history of the area goes back to the early 1800’s and is sketchy at best during those early years
