1915 Map of Wallulah

About this map

The confluence of the Snake River and Columbia River serves as the focal point for this 1915 survey of southeastern Washington. A dense network of competing rail lines, including the Spokane Portland and Seattle RR and the Northern Pacific RR, traces the riverbanks and cuts through the interior, defining the early 20th-century economy of the Walla Walla valley. The map reveals the logistical importance of river-adjacent settlements like Two Rivers and Wallula, where infrastructure such as Tunnel No 8 and Tunnel No 9 overcome the rising terrain. Further inland, the agricultural landscape is dotted with small rural hubs like Gardena and Eureka, alongside numerous localized education centers including Smith School and Willow School. This sheet details the intersection of regional water rights and steam-era transport just before modern irrigation and dam projects fundamentally altered these river corridors.
