About this map

Naval Weapons Systems Training Facility lands dominate this corner of Morrow County, where military operations and desert conservation meet. In this early 1990s landscape, the Umatilla National Wildlife Refuge borders the high desert terrain, marked by scattered water sources like Coyote Spring and Lower Sand Spring. The settlement of Clarke and the nearby Boardman Junction serve as points of orientation amidst a network of rural routes including Paterson Ferry Road and Homestead Road. Infrastructure for agriculture and defense is prominent throughout, from the West Extension Irrigation Canal to a dedicated Rifle Range and Landing Strip. This geography illustrates the transition from the river-adjacent refuge lands to the expansive high-desert installations of the Umatilla Activity Depot.
