Grand Coulee at the higher side of the flexure. Encountering the steep slope of the monocline, the new river would have cascaded off the rim, down onto a broad plain where Coulee City and Dry Falls State Park now stand. Upper Grand Coulee began as an cascade just north of Coulee City. As the rush of water eroded the surface, it steepened into a waterfall. The falls continued to erode backward (northward) creating the canyon.

Grand River (Michigan) conducted studies and explains resulted as it moves downstream. The expedition offered presentations, displays and demonstrations to communities along the river in an attempt to interact with the river, its tributaries, and its people throughout the watershed.
