The Ice Age Flood
At the end of the last Ice Age, some 12,000 years ago, one or more cataclysmic floods occurred in what is now the northwest region of the United States, leaving a lasting mark of dramatic and distinguishing features on the landscape of parts of the States of Montana, Idaho, Washington and Oregon. The National Park Service has created an Ice Age Flood Geologic Trail tracing the route of the flood. My book provides photographs and descriptions of the features in Oregon and Washington. The cover photograph is Palouse Falls.

Ice Age Flood Tour
As a Park Ranger at Lake Roosevelt National Recreation Area, I became fixated on the Ice Age Flood that completely changed the landscape of eastern Washington. I compiled this tour of the flood from Portland, Oregon, through the Channeled Scablands and back to Portland.
