2020 Map of Sperry

About this map

Sperry and Harder are primary points of reference on this landscape of eastern Washington, situated along the diagonal path of the Columbia Plateau State Park Trail. This trail follows a historic transportation corridor that connects small locales like McAdam and Wacota, tracing the relief of the plateau. The terrain is defined by deep geological cuts such as Skookum Canyon and Collier Coulee, which disrupt the agricultural grid pattern established by local roads like S Bauer Rd and Gill Rd. Near the settlement of Harder, Harder Spring provides a rare mapped water source in this dry environment. The presence of the Fisher Ranch Airport in the northern portion of the quadrangle indicates the ongoing importance of private aviation for managing large landholdings across the Adams and Franklin county line.
