About this map

Joint Base Lewis-Mcchord dominates the central landscape of this Umatilla County quadrangle, where military infrastructure meets the engineered hydrology of the Columbia Basin. The area is defined by a sophisticated network of water management, with the West Extension Irrigation Canal in the northwest, the Westland A Canal to the east, and the High Line Canal cutting through the southern sections. These waterways represent the vital lifelines for agriculture in the high desert, enabling local homesteading indicated by routes like Homestead Rd. In the northeast, the natural topography of Coyote Coulee provides a sharp contrast to the geometric grid of access roads and military boundaries. Transportation is centered on thoroughfares such as Stafford Hansel Rd and Irrigon-Ordnance Rd, while the K2 Airport serves the region's aviation needs near the southern margin.
