USGS Topo · Published 1971About this map
Upper Grand Coulee dominates the southeastern quadrant of this late 1960s survey, showing the submerged landscape of Banks Lake as mapped by the U. S. Bureau of Reclamation. The map details the intricate topography of the channeled scablands, where Barker Canyon and Foster Coulee cut through the basalt plateaus. At the southern edge, the iconic Steamboat Rock rises above the reservoir waters, marking a significant geological boundary near the Grant and Douglas County line.
