About this map

The Montana-Wyoming state line cuts directly across this 1970 survey, capturing a remote landscape defined by the drainage systems of Three Bar Creek and Horse Creek. This is a terrain of quiet industrial utility and ranching heritage, centered on the Three Bar Ranch and the administrative boundary between Powder River County and Campbell County.

The presence of numerous labels for Drill Hole and Well across the sections suggests the subsurface exploration and water infrastructure necessary for life and industry in this high-plains environment. The branching waterways of the Buffalo Creek, North Fork, and South Fork illustrate the complex natural irrigation of the borderlands during the early 1970s, providing a clear record for researchers tracing historical land use or property boundaries along the interstate divide.
