Irby serves as the focal point of this Eastern Washington landscape, situated along the meandering course of Crab Creek. The terrain is defined by the unique Coulee geology characteristic of the region, where water features like Bobs Lakes and Lake Cr provide rare moisture in a landscape primarily partitioned into large agricultural blocks. This 2020 edition provides a clear record of the local transportation network, showing how historic routes like Old Hwy Lp and Irby Rd connect the area's rural farmsteads. The southern portion of the map highlights the survey boundary between Lincoln and Adams counties, primarily following Davis Rd. While most of the sheet is occupied by the expansive open country of the Big Bend region, the concentration of family-named roads such as Schafer Rd, Fink Rd, and Kagele Rd N offers a modern link to the long-standing farming families of the plateau.
