1979 Map of Blackstone Reservoir

About this map

Blackstone Ranch and its namesake reservoir sit at the center of this 1970s landscape in Owyhee County. The area is defined by a network of seasonal watercourses and drainage features like Juniper Draw and Louse Creek, which navigate the arid expanse of the Blackstone Desert. This high-desert terrain is marked by a sparse infrastructure of unpaved transit, with the Grasmere Road and Blackstone Road serving as the primary lifelines for the isolated ranching operations.
