About this map

Ordnance sits at the center of this high-desert landscape in Umatilla County, where the transition from arid coulees to irrigated agricultural land is clearly visible. The terrain is defined by geological features like Coyote Coulee and Fourmile Canyon, while the human footprint is marked by an extensive network of water management systems. A series of significant waterways, including the W Extension Irrigation Canal, Westland A Canal, and High Line Canal, demonstrate the region's reliance on engineered irrigation to support its development.

Transportation corridors like the Irrigon-Ordnance Rd and Stafford Hansel Rd connect the settlement to the surrounding county, cutting across the township lines of t4n r27e and t3n r27e. This 2017 survey also captures more remote landmarks like Lost Lake and a grid of rural routes such as Desert Rd and Homestead Ln, which trace the history of land use and settlement in this portion of eastern Oregon.
