Cliffs on "Old Highway 10", in the Yakima River Valley. These cliffs are composed of river deposits (alluvium) of redeposited volcanic ash and rock much like what was in the rivers after Mt. St. Helens erupted- excellent and beautiful example of flood deposits shortly after a nearby volcanic eruption in the cascades. - Blowout Bench Airport fotogalerij
