The Columbia River forms the northern lifeline of this mid-century landscape, dominated by the rise of infrastructure and military installations during the early Cold War. Recent engineering projects like McNary Dam near Umatilla and Power City have reshaped the river's flow, while the inland territory is defined by the massive footprint of the Umatilla Ordnance Depot and the Boardman Bombing and Gunnery Range.
