1965 Map of Tule Prong

About this map

The Yakima Indian Reservation Boundary and the Old Indian Treaty Boundary intersect the high plateau country of south-central Washington on this mid-1960s survey. The landscape is defined by deep incisions like Stone Canyon and Tule Canyon, where seasonal drainage systems like Tule Prong flow toward the Columbia River basin. This survey documents the rural infrastructure of the era, including the Dorothy Sch and Glade Cem near Glade Creek. The road network consists primarily of named gravel and dirt routes such as Smith Road and Johnson Road, tracing the flat tops of ridges like Jerry Kimbrell Ridge before descending into the dramatic canyon topography. Evidence of local agriculture is seen at the Storage Bins located near the headwaters of the prong.
