Ice Age Floods Field Trip:Western Columbia Plateau
Follow part of the path of one of the greatest floods known to geology. We will travel through the Othello and Drumheller Channels. Continue across the mouth of the Grand Coulee, over Pinto Ridge to Dry Falls and down the Lower Grand Coulee. See giant ripples on the West Bar and dry cataracts of Potholes Coulee and Frenchman Coulee, then through Frenchman and Sentinal Gaps down the Columbia River and back. Bring a
lunch, drinks and snacks. A small under-seat size cooler is acceptable.
