Similar potholes are encountered in riverbeds and the Channeled Scablands scoured by glacial outburst floods. Lenore Canyon is a coulee associated with the development of the Scablands. Turnbull NWR encompasses more than of the Channeled Scablands. Unique erosion features, called channeled scablands, are attributed to these amazing floods. They also formed many unusual geological features, such as the channeled scablands of eastern Washington. Numerous flat-topped buttes with rich soil stand high above the chaotic scablands. Depressions were scoured out within the scablands that resemble virtually circular steep-sided potholes. The giant current ripple marks are important depositional forms in diluvial plain and mountain scablands. Bretz conducted research and published many papers during the 1920s describing the Channeled Scablands. Lincoln County lies on the Channelled Scablands, known as the Big Bend Plateau. He made important discoveries regarding the origin of the Channeled Scablands. The morphology of the scablands is butte-and-basin. It took three days to pass through the Channeled Scablands.
