About this map

Grand Coulee dominates this landscape, where the massive expanse of Banks Lake fills the ancient chasm between basalt cliffs. The topography is defined by sharp elevation changes, most notably at the iconic Steamboat Rock, which rises as a prominent plateau above the water's surface. Along the eastern shoreline, the terrain is marked by smaller geological formations such as the Devils Punch Bowl and the steep descent of Paynes Gulch.

Modern infrastructure follows the contours of the coulee floor, with Coulee Blvd and the Steamboat Rock Park Entrance Rd providing access to the shoreline and recreational areas. The surrounding tablelands are dissected by drainage systems including Lower Lewis Creek, Rusho Creek, and Ladds Creek. This survey captures the intersection of the Douglas and Grant county lines as they cross the high desert and flooded coulee floor.
