2020 Map of Steamboat Rock SW

About this map

Banks Lake dominates the central portion of this landscape, a significant reservoir filling the Grand Coulee floor. The eastern shore is marked by the massive basalt formation of Steamboat Rock, while the water's edge includes sheltered features like Devils Punch Bowl. This 2020 record illustrates the modern infrastructure serving the area, including Coulee Blvd and the Steamboat Rock Park Entrance Rd, which facilitate access to the recreational and geographical landmarks along the coulee. Several small drainages, including Rusho Cr, Ladds Cr, and Lower Lewis Cr, flow toward the lake from the surrounding high plateaus. The map also delineates the boundary between Douglas and Grant counties, cutting through the western upland terrain north of 13th Rd NE.
