2020 Map of Marlin SW

About this map

Black Rock Coulee defines the drainage and topography of this landscape in eastern Washington, where the high desert meets the structured agricultural grid. This 2020 record reflects a modern rural environment where historic travel routes like Old Hwy Lp and Black Rock Rd intersect with a sparse network of county roads. The map illustrates the convergence of three counties—Grant, Lincoln, and Adams—marking a significant jurisdictional boundary point just north of W Davis Rd. The land is meticulously partitioned by the Public Land Survey System into townships and sections, including t21n r31e and t20n r31e, showcasing a legacy of land division that has shaped the region's farming and ranching identity. Researchers will find a highly detailed view of the local road system, from Graedel Rd to Kissler Rd, providing a clear look at the infrastructure supporting this remote part of the Columbia Basin.
