About this map

Military installations and irrigation infrastructure define this section of Morrow County, where the settlement of Clarke sits at a crossroads of water management and tactical training grounds. The southern portion of the map is dominated by the Naval Weapons Systems Training Facility Boardman, while the northeast corner marks a boundary for Joint Base Lewis-Mcchord. This landscape is heavily shaped by the West Extension Irrigation Canal and the Boardman Canal Rd, reflecting the critical role of water diversion in the high desert.

Transportation routes such as Paterson Ferry Rd and Lewis & Clark Dr cut across the arid terrain, connecting the interior to the Columbia River corridor. The presence of Lower Sand Spring and Upper Sand Spring indicates natural water sources that preceded the modern canal systems. Along the northern edge, the Umatilla National Wildlife Refuge provides a managed sanctuary, contrasting the heavy equipment and training focus of the adjacent naval facility.
