Authored by historian William Denison Lyman, The Columbia River: Its History, Its Myths, Its Scenery, Its Commerce provides an expansive early 20th-century portrait of the Pacific Northwest's most vital waterway. The book chronicles the transformation of the mighty river from a wild, mythic landscape navigated by indigenous tribes and early fur traders into a heavily domesticated artery of steamboat commerce and regional agriculture. Through a blend of recorded Native American legends, pioneer chronologies, and glowing descriptions of geographic grandeur, the text captures the prevailing frontier optimism regarding the industrial subjugation of nature. A keen insight drawn from the work is how the juxtaposition of indigenous mythology and modern commerce exposes the inherent paradox of frontier boosterism; by romanticizing Native American legends as vanishing antiquities while simultaneously celebrating the aggressive industrial development of the river, the narrative illustrates how early historians actively mythologized the region's past to justify its colonial and ecological conquest.
