1970 Map of Harmon NW

About this map

The Old Indian Treaty Boundary slices across the landscape of Ellis County, marking a historic line of demarcation in this corner of Oklahoma. Surveyed around 1970, the area shows a distinct transition between agricultural grazing land and emerging energy extraction. Drainages like Wolf Creek and Little Wolf Creek wind through the township sections, punctuated by family-named landmarks such as Austin and Benton. This landscape is defined by its industrial footprint, featuring a significant Pipeline network and numerous scattered Gas Wells. For those studying the land use of the early 1970s, the map provides precise locations for various extractive sites, including several Gravel Pits and a Sandpit, alongside benchmark elevations like BM 2472 that reveal the Subtle topographic shifts of the High Plains.
