1957 Map of Nefsy Divide

About this map

Black Hills National Forest land dominates the northern portion of this 1950s survey, where rugged topography is defined by a series of prominent ridges including Schoepf Divide, McFarland Divide, and Sunny Divide. The landscape transitions from these forested heights into a complex network of ranching and early energy development in the south. The presence of the Barton Oil Field and scattered Gravel Pits alongside small-scale ranching outposts like Zimmerman Ranch and Ames Ranch illustrates the varied mid-century land use in Crook County.
