Geology

The impacts of geology are everywhere we look. Geological processes have helped form the earth beneath our feet and the hills, valleys, mountains, and plains where we live and recreate. Whitman Mission NHS is located within the Columbia Plateau, the geologic region that makes up much of Washington, Oregon and Idaho. The evidence of geologic forces can be seen at Whitman Mission, from the powdery soil composed of loess, to the flat river plain, to the how and why of the hill within the monument. Each formed through different methods that have shaped our Earth over billions of years.
