1915 Map of Prosser
USGS Topo · Published 1957About this map
The Yakima River carves a fertile corridor through this 1915 survey, defining a landscape bounded by the Rattlesnake Hills to the north and the Horse Heaven Hills to the south. This era shows the early development of irrigation and transport in the region, with the Sunnyside Canal and Sunnyside Road supporting a growing network of agricultural settlements. The towns of Prosser, Grandview, and Mabton serve as hubs for the surrounding farmsteads, while the Northern Pacific and Union Pacific railroads provide the vital infrastructure for moving goods out of the valley.
