Lake Umatilla and the Columbia River dominate this early 1960s landscape, illustrating the critical water-management infrastructure along the Oregon-Washington border. The settlement of Boardman serves as a central hub, flanked by the Union Pacific railroad and the vast Boardman Bombing Range to the south. This military presence, marked by a defined Naval Reservation Boundary, exists alongside an extensive agricultural network of canals, including the West Extension Irrigation Canal, which draws water from the river to support the desert interior.
