The Great Escape Geology Tour

Saturday, September 9th, 8:00am - 5:00pm
@ Wenatchee Valley Museum & Cultural Center

Ice Age Floods, using the Grand Coulee and the Upper Crab Creek drainages, filled the Quincy Basin at a rate up to 16.5 million cubic meters of water per second. This tour will examine the incredible erosive consequences of the floodwaters escaping the Quincy Basin, via Lynch, Potholes and Frenchman Springs Coulees. In addition, it examines the eight mile wide Drumheller Channels, through which most of the Quincy Basin floodwaters drained largely down the Lower Crab Creek drainage, toward the Columbia River at Beverly, Washington. Cunderla and  Lacy lead this tour.
