About this map

Clarke sits at the nexus of water management and transportation in this high desert landscape of Morrow County. The area’s reliance on groundwater and engineering is evident through the presence of Upper Sand Spring, Lower Sand Spring, and Coyote Spring, which historically supported life in this arid region. The W Extension Irrigation Canal cuts across the northern terrain, following the alignment of Boardman Canal Rd, illustrating the complex network of water rights and infrastructure essential for local agriculture.

Modern infrastructure dominates the southern half of the map, where the heavy corridor of the Interstate is flanked by Frontage Rd. Older transit legacies are preserved in names like Lewis & Clark Dr and Paterson Ferry Rd, which suggest the historic routes used by early travelers heading toward the Columbia River. The intersection of these legacy roads with modern thoroughfares like Bombing Range Rd highlights the changing utility of this Oregon landscape over the decades.
