2017 Map of Barker Canyon

About this map

Banks Lake dominates the southern landscape of this Grant County region, where the steep basalt walls of the Upper Grand Coulee meet the open plateau. The terrain is defined by dramatic geological remnants such as Steamboat Butte and the landmark Steamboat Rock at the water's edge, illustrating the glacial flood history of the Columbia Basin. Barker Canyon cuts a deep path through the center of the sheet, leading past Barker Canyon Lake toward the larger reservoir. This 2017 survey reveals a sparsely populated area characterized by local access routes like Barker Canyon Rd and Rd 26 NE that navigate the high ground above Foster Coulee. The map provides a precise view of the complex topography and drainage patterns between Barker Butte and Cache Butte, detailing the transition from high arid plains to the coulee floor.
