2015 Map of Open A Ranch

About this map

Thunder Basin National Grassland dominates the southern half of this landscape, where the high plains are carved by the intermittent drainage of Black Thunder Cr. Centered around the eponymous Open A Ranch, the area reveals a pattern of modern water management essential for high-desert ranching, featuring several family-named catchments such as Spath Reservoir, Smith Reservoir, and The Robb Reservoir. The geography is defined by a series of long, parallel drainage systems including Cottonwood Cr and Bacon Cr, which flow northward across the township lines. Transportation across this corner of Campbell County relies on primitive routes like Keeline Rd and Lawver Rd, which provide access to the remote pastures and isolated homesteads that characterize this section of the Wyoming range.
