Authored in 1928 by prominent Oregon journalist and historian Fred Lockley, History of the Columbia River Valley from the Dalles to the Sea is an exhaustive, multi-volume subscription history detailing the commercial and civic maturation of the region's most vital geographic artery. Tracing the lower Columbia corridor's evolution from the era of maritime exploration and the fur trade to the booming industrialization of Portland and Astoria, Lockley leverages his extensive career interviewing early settlers to weave personal pioneer reminiscences into a broader narrative of regional development. Like many commercial histories of its era, the primary historical account is heavily subsidized by subsequent volumes of flattering biographical sketches profiling local merchants, industrialists, and pioneer descendants, serving as a sprawling civic monument to the capitalist triumph of the local elite.

A keen insight drawn from the work is how Lockley’s narrative structurally redefines the Columbia River itself, conceptually transforming it from an ancient, highly complex network of Indigenous civilization and sustenance into a mere logistical conduit for Anglo-American capitalism. By framing the "history" of the river valley almost exclusively around the establishment of trading posts, the advent of steamboat navigation, and the extraction of timber and salmon for global markets, the text actively erases millennia of Chinookan and other Native sovereignties. This historiographical maneuver successfully commodifies the landscape, validating the colonial project by teaching readers that the true destiny of the great river was not to sustain the Indigenous societies that had managed it for centuries, but to serve as a passive, exploitable highway for modern industrial empire.
