Banks Lake dominates the central topography of this 2014 survey, illustrating the vast engineered water system of the Grand Coulee area. The massive plateau of Steamboat Rock rises prominently in the northeast, a geological landmark that defines the local landscape and serves as the centerpiece for the Steamboat Rock Park Entrance Rd. The terrain is marked by sharp elevation changes between the high desert plateaus of Douglas Co and the reservoir basin in Grant Co.
