The first part of the Yakima Scenic Byway through southern Washington dips south across a section of the Yakama Nation Reservation, created as a result of a treaty signed in 1855, and over the Simcoe Mountains. Exiting the reservation, US 97 traverses Satus Pass, which, at 3,107 feet, affords views of prairie lands and long-range vistas of Mt. Saint Helens and Mt. Rainier.
