2017 Map of Babcock Ridge

About this map

The Columbia River carves a deep path along the western edge of this central Washington landscape, defining the dramatic topography where the high basalt plateau of Babcock Ridge drops toward the water. At the base of these cliffs, the recreational settlement of Crescent Bar occupies a distinct river terrace, while the surrounding terrain is marked by the unique geomorphology of the Potholes Coulee. This area is characterized by a complex network of small water bodies and catchments, including the Evergreen Reservoir, Quincy Lake, and the interestingly named Judith Pool. The eastern flats show a transition to managed land use with the presence of the Quincy Flying Service. The map traces the intricate drainage patterns of the region, from the deep cuts of Lynch Coulee to the scattered basins of Ancient Lake and Dusty Lake, reflecting the legacy of prehistoric flood events that shaped this part of Grant County.
