2017 Map of Steamboat Rock SW

About this map

Banks Lake dominates the central coulee of this Grant County landscape, providing a clear view of the mid-20th-century irrigation and recreation infrastructure in eastern Washington. The sheer basaltic profile of Steamboat Rock stands as a massive landmark in the northeast, while smaller water bodies like Thompson Lake and Higginbotham Reservoir dot the surrounding high desert terrain. The map details the local road network, including Coulee Blvd and the Steamboat Rock Park Entrance Rd, which provide access to the water's edge and the surrounding plateau. Subtle drainage patterns such as Paynes Gulch, Rusho Cr, and Lower Lewis Cr reveal the complex hydrology of the Grand Coulee area. The boundary between Douglas Co and Grant Co is clearly demarcated, showing how these political lines intersect with the dramatic natural features of the Columbia Basin.
