1941 Map of Yakima East

About this map

The Yakima River carves a critical corridor through the high ridges of central Washington, anchoring the region's early 20th-century agricultural and industrial expansion. The city of Yakima and nearby Union Gap serve as the hub for this valley, where the Northern Pacific and Union Pacific railroads meet. The landscape is defined by an intricate network of irrigation, including the Cascade Canal, Moxee Canal, and the Roza Canal, which transformed the arid flats between Yakima Ridge and the Rattlesnake Hills into productive farmland. Rural life is evidenced by family-named roads such as Postma Road and Beauchene Road, alongside community centers like the First Reformed Ch and Central School. To the south, the boundary of the Yakima Indian Reservation sits against the base of Ahtanum Ridge, marking a distinct shift in the valley's complex land-use history.
