About this map

Black Rock Coulee cuts a distinct path through this section of the Channeled Scablands, where the borders of Grant, Lincoln, and Adams counties converge. The landscape is defined by the sharp basalt coulees and dry washes typical of this corner of Washington, with Crab Creek appearing in the northern portion of the survey. The mapping reveals a sparse but rigid network of section-line roads and family-named routes, such as Black Rock Rd and Kissler Rd, which navigate the elevation changes between the high plateaus and the coulee floor. This modern record captures the enduring agricultural and ranching layout of the region, where the vastness of the terrain is marked by remote bypasses like Old Hwy Lp and the intersection of Bates Rd E and Graedel Rd.
