2013 Map of Blackstone Reservoir

About this map

Blackstone Ranch serves as a lone marker of habitation in this arid expanse of Owyhee County, situated near the seasonal waters of Blackstone Reservoir. The landscape is defined by its drainage patterns and distinct topographic depressions, most notably the Big Holes and the carved terrain of Juniper Draw. To the east, the elevation shifts into the arid Blackstone Desert, while the southern reaches of the quadrangle transition into the high-elevation terrain of Bighorn Country. This 2013 survey illustrates the remote character of southwestern Idaho, where water sources like Louise Cr, Nit Cr, and Sheep Cr dictate the layout of the few established ranching outposts and primitive roads. The map provides a clear view of the Public Land Survey System grid, including the boundaries of t11s r5e and t11s r6e, which organize this vast territory.
