1973 Map of Grassy Ridge

About this map

South Fork Owyhee River carves a deep, winding path through the southwest corner of this landscape, marking a sharp transition from the elevated Grassy Ridge and the arid expanse of the Owyhee Desert. The map documents a sparsely populated ranching environment where life and movement are tied to isolated water sources like Shea Res, Coyote Flat Res, and Coyote Hole Res. Near a sharp bend in the river, the 45 Ranch stands as a primary hub of activity, supported by a nearby Corral and the 45 Landing Strip. High-clearance Jeep Trail networks provide the only access across Coyote Flat, illustrating the remote nature of this high-plateau region during the early 1970s.
