2021 Map of Open A Ranch

About this map

Open A Ranch sits at the heart of this high plains landscape in Campbell County, where the topography is defined by the complex drainage systems of the Powder River Basin. The map illustrates a transitional ranching environment largely encompassed by the Thunder Basin National Grassland. Water management is central to the area's utility, evidenced by a series of named catchments including Spath Reservoir, Smith Reservoir, and The Robb Reservoir, which support livestock in an otherwise arid expanse. The terrain is deeply etched by numerous seasonal waterways such as Black Thunder Creek and Cottonwood Creek. Transportation through these grasslands relies on a sparse network of established routes like Keeline Rd and Lawyer Rd, which connect the remote ranching outposts to the wider region. This survey provides a modern view of the land use patterns and grazing boundaries that continue to shape northeastern Wyoming.
