About this map

Upper Grand Coulee defines this portion of the Columbia Basin, where the massive waters of Banks Lake are contained within the high basalt walls of the coulee. The landscape is marked by dramatic geological formations like the Devils Punch Bowl and the deeply carved Northrup Canyon. Away from the main coulee, the high plateau is crossed by ephemeral drainages such as Devils Creek and Rusho Creek, which cut through the sagebrush-dominated terrain.

Evidence of early settlement and ranching families remains in the presence of the Thompson-Shrock Cem and Saint Johns Cem, located near the intersection of Rd 49 Ne and Rd 48 Ne. These small burial grounds, along with the family-named Paynes Gulch, indicate a history of dryland farming and homesteading in a region primarily shaped by the massive irrigation and power projects of the mid-20th century.
