1910 Map of Zillah

About this map

The Yakima River valley serves as the central artery for this early twentieth-century landscape, where new irrigation systems like the Sunnyside Canal began transforming the arid terrain into a productive agricultural corridor. The Northern Pacific railroad parallels the river, anchoring a string of growing settlements including Toppenish, Wapato, and Zillah. This survey provides a clear view of the complex land use at the time, with the extensive Yakima Indian Reservation occupying the southern half of the quadrangle. High elevation landmarks such as Toppenish Ridge and the Horse Heaven Hills rise sharply from the valley floor, while smaller details like a remote sawmill and the Old State Road reveal the early infrastructure supporting the timber and transit needs of Yakima and Klickitat counties.
