2011 Map of Steamboat Rock SW

About this map

Banks Lake dominates this Grant County landscape, showing the vast reservoir's western reaches as they appeared in 2011. The prominent geological formation of Steamboat Rock stands at the northern edge of the sheet, surrounded by the waters of the lake and neighboring Thompson Lake. The map reveals a transition from the water's edge to the high desert terrain of the Coulee region, characterized by drainage systems like Rusho Creek and Ladds Creek. To the southeast, the Higginbotham Reservoir Dam controls local irrigation and water flow, reflecting the area's agricultural infrastructure. Modern recreation is evidenced by the Poplar Picnic Area and the winding Steamboat Rock Park Entrance Rd, providing a detailed look at the infrastructure supporting visitors to this unique basalt plateau.
