About this map

Umatilla Depot Activity dominates the central landscape of this Eastern Oregon survey, defined by its massive grid of storage structures and supporting infrastructure. This military installation, located near the Ordnance settlement, reflects the specialized logistical role the region played throughout the mid-to-late 20th century. The terrain is marked by the distinct Coyote Coulee and organized by an extensive network of water management, including the Irrigon Canal and the Lost Lake Canal which draw from the nearby Columbia River system to support agricultural development in an otherwise arid landscape.

Industrial activity is evident through numerous Gravel Pits scattered near the Morrow Co Umatilla Co border. Local transportation and small-scale settlement patterns are visible at Munley and Westland, with a dedicated Landing Strip and Homestead Road indicating the dual reliance on aviation and traditional ranching or farming routes. The presence of Lost Lake and various Sewage Disposal Ponds underscores the intensive human modification required to manage water resources in this desert environment.
