Join us as we explore Ice Age floods in the Western Quincy Basin. Ice Age floods entered the Quincy Basin from the northeast and east. Some of this water drained from the basin through the Drumheller Channels to the south. The remainder flowed west, exiting the basin through Frenchman Coulee, Potholes Coulee, and Crater Coulee on the western edge of the Quincy Basin. We will examine the landforms and sediment evidence for late Ice Age catastrophic flood origins and evolution of the western flood outlets. Along the way, you will see giant basalt columns, dry falls, potholes, plunge pools, buttes, mesas, flood bars, dunes, and more. Additionally, we will examine evidence of earlier Ice Age floods into the Quincy Basin from the Columbia River Valley.
