Evergreen Ridge dominates the northern landscape of this Central Washington terrain, where the arid high desert meets a series of significant water bodies and coulees. The southwestern corner of the sheet reveals the sharp descent into the Columbia River valley at Wanapum Lake, marked by the dramatic geological formations of Frenchman Coulee and Frenchman Spring. These features illustrate the erosion and flood-carved history of the region's basalt layers.
