About this map

Irby sits at a geographic crossroads in eastern Washington, where the serpentine course of Crab Creek carves through the basalt-edged coulees of the Channeled Scablands. This modern topographic record captures the transition between the rolling agricultural uplands of Lincoln County and the northern edge of Adams County. The landscape is defined by the canyon floor through which Crab Creek flows, joined from the north by the deep-set drainage of Lake Creek.

A network of gravel and local connectors like Old Hwy Lp and N Batum Rd serves the isolated farmsteads and agricultural allotments that dominate the area. The section lines of the Public Land Survey System are clearly marked, showing the division of the interior plateaus where roads such as Kagele Rd N and Fink Rd follow the rigid grid of the high desert wheat country. The boundary between Lincoln and Adams County is traced along Davis Rd, anchoring the southern portion of the survey.
