1965 Map of Triangle

About this map

The Silver City Range dominates this mid-1960s survey of Owyhee County, providing a detailed look at the high-desert terrain and the infrastructure that supported local ranching and mining operations. Centered on the settlement of Triangle, the map reveals a network of primitive transportation routes, including the French Grade and numerous jeep trails that traverse the complex topography of China Butte and Quicksilver Mtn. The presence of the Triangle Airstrip and landmarks such as the Afterthought Mine suggest a landscape where isolated industrial sites and livestock management define the human footprint.
