1971 Map of Eagle Rock

USGS Topo · Published 1975

About this map

Osborn Ranch sits in the northern reaches of this high plains landscape in Campbell County, where the drainage patterns of the Belle Fourche River and Rattlesnake Creek define the topography. By the early 1970s, the region was undergoing a significant industrial shift as the Hilight Oil and Gas Field expanded across the southern half of the map. Numerous Oil Wells and a central Pipeline indicate the intensifying extraction efforts of the era, contrasting with the traditional ranching heritage of the area. Notable landmarks like Eagle Rock and the winding course of Hay Creek provide natural orientation points amidst the developing energy infrastructure. The map also records early supporting facilities such as a Pumping Sta and a Gravel Pit, reflecting the physical changes brought by resource development in Wyoming's Powder River Basin region.
