This image was taken from the top of Saddle Mountain looking southwest toward Rattlesnake Ridge. During the Missoula Floods, the water level of Lake Lewis between these two ridges was about 600 feet above the current basin floor.
As I was photographing on top of the mountain, I felt a cold wind pick up. The skies turned dark and I could see the rain coming toward me. I decided it was a good time to pack up my gear and head down the steep gravel/dirt road before it turned to mud. It was the end of a good day and a great trip driving around the Pasco basin exploring for traces of the Ice Age floods.
