Organization: Wenatchee Valley Museum
The Umptanum Ridge Water Gap, also known as the Yakima River Canyon is the main feature of this geology tour. Guests will explore some spectacularly beautiful and rugged terrain while learning the unique and powerful natural forces at work in the landscape. Learn how the rule of geologic precedence sets the stage for a flat-land meandering river to become a frozen-in-place meander at the bottom of a deep canyon surrounded by the Manastash, Umtanum, Yakima and Ahtanum ridge tops. Besides visiting locations in the canyon, the tour will stop at the Ginkgo Petrified Forest Interpretive Center at Vantage. Talking points include glacial moraines, ancient volcanoes, Yakima fold belt, anticlines, synclines, Columbia River and Ellensburg formation basalt flows.
