1966 Map of J Y Ranch

About this map

The South Wichita River and the Middle Fork Wichita River define this ranching and petroleum landscape in King County. In the mid-1960s, the vast J Y Ranch dominates the terrain, supported by the J Y Ranch South Camp and the J Y Masterson Landing Field. Evidence of industrial activity is centered on the Bateman Oil Field in the southwest, where numerous Oil Wells and Drill Holes are noted alongside a growing network of pipelines. Transportation across this remote country is limited to a handful of routes, including the Newman Trail and several jeep trails, reflecting a time when the region was primarily accessed for cattle operations and oil exploration. Revisions from 1979 purple-ink updates show continued development in the area's resource extraction infrastructure.
