1917 Map of Pasco

About this map

The Columbia River and Yakima River converge in this early 20th-century landscape, where the irrigation of the arid Horse Heaven Hills began to shape the region's agricultural future. This 1917 edition, surveyed earlier in 1904 and 1914, highlights a developing rail-and-water economy centered on Pasco and Kennewick. The map documents numerous rural educational sites, including Triple Springs School and Locust Grove School, which served the scattered ranching communities. Water infrastructure is central to the area's growth, evidenced by the Horn Rapids Ditch and the Pacific Coast Pipe Line. Transportation is dominated by the Northern Pacific and the Oregon Washington Railroad and Navigation Company, alongside river crossings like the Zimmerman Ferry. Named family landmarks such as Rosenzweig Ranch and Grosscup Ranch offer specific points of interest for genealogists tracing the early settlement of Franklin and Benton counties.
