1965 Map of Osha Mountain

About this map

Carson National Forest dominates this mid-1960s landscape, where complex land grant boundaries meet the rugged topography of the Rincon Mountains. The map documents a sparsely settled region defined by the convergence of several major land holdings, including the Beaubien and Miranda (Maxwell) grant and the Rancho del Rio Grande. In the eastern valley, the settlement of Black Lake serves as a focal point near the San Antonio Ch, while a network of pack trails and jeep trails provides access through high-altitude terrain at Osha Pass and Quintana Pass. Numerous watercourses, such as Coyote Creek and Cieneguilla Creek, carve through the high country, creating a drainage pattern that historically dictated the movement of livestock and people between these isolated mountain parks and the larger valley basins.
