About this map

The Umatilla Ordnance Depot dominates this high-desert landscape near the border of Morrow and Umatilla counties. This mid-century survey illustrates the industrial and military infrastructure of Eastern Oregon, centered on the specialized settlement of Ordnance. The area is bisected by the Union Pacific railroad, which parallels a series of vital water management systems including the West Extension Irrigation Canal and the High Line Canal.

Evidence of local resource extraction and military utility is clear through the numerous Gravel Pits and the presence of an Airstrip near the main depot complex. The terrain transitions from the stark depression of Coyote Coulee in the north to the seasonal Lost Lake in the south. This edition includes 1970 revisions shown in purple, documenting changes to the depot's structural footprint and the surrounding road network as the facility evolved during the Cold War era.
