2020 Map of Ordnance

About this map

Agricultural infrastructure and water management define this portion of the Columbia Basin along the boundary of Morrow and Umatilla Counties. The landscape is heavily marked by irrigation engineering, notably the W Extension Irrigation Canal in the northwest and the Westland A Canal to the east, which support the geometric field patterns of the surrounding plateau. Local transit is facilitated by a network of rural routes such as Irrigon-Ordnance Rd and the aptly named Desert Rd, reflecting the arid environment that necessitated these water projects. Natural drainage features like Coyote Coulee and Fourmile Canyon interrupt the otherwise orderly grid of section lines and frontage roads. The map provides a clear look at the intersection of early 21st-century logistics and historic land divisions, evidenced by named thoroughfares like Stafford Hansel Rd and Homestead Ln.
