2017 Map of Ephrata SW

About this map

Beezley Hills dominates the central landscape of this Grant County region, reflecting the characteristic basalt formations and coulee topography of central Washington. The southern portion of the map reveals the complex water infrastructure of the Columbia Basin Project, specifically the Quincy Lateral Canal which cuts through the arid landscape to support regional agriculture. A network of rural roads, including Wheatland Rd and Sagebrush Flats Rd, follows the section lines of the Public Land Survey System, illustrating how modern habitation and transit are superimposed on the prehistoric landforms of Lynch Coulee and Two Springs Canyon. Small water sources like Two Springs remain critical landmarks in this high-desert environment, where the elevation changes are captured by the detailed contours of the USGS survey.
