1979 Map of Toppenish

About this map

Fort Simcoe Historical State Park stands as a focal point of early regional history within the expansive Yakima Indian Reservation, where the landscape transitions from the high peaks of Simcoe Mountain to the agricultural valleys of the Yakima River. By the late 1970s, the irrigation network including the Toppenish Canal and Sunnyside Canal had deeply shaped the local economy, supporting a string of settlements from Wapato and Toppenish to Sunnyside. The map illustrates a complex intersection of transportation and conservation, featuring the Burlington Northern railroad lines running parallel to the river and the protected lands of the Toppenish National Wildlife Refuge. From the northern Rattlesnake Hills to the southern Horse Heaven ridge, the terrain is marked by numerous named canyons like Coyote Canyon and Island Canyon, providing a detailed look at the geographical barriers that directed the path of development in Yakima and Klickitat counties.
