1967 Map of Osier

About this map

The Denver and Rio Grande Western railroad threads through this high-altitude landscape of southern Colorado, following the dramatic contours of the Los Pinos River canyon. Near the small outpost of Osier, the topography is defined by the massive presence of Spruce Mountain and Osier Mountain, which rise sharply above the river valleys. The 1967 survey highlights the area's role as a working forest and rangeland, evidenced by the La Manga Stock Driveway and the Trail Gulch Cow Camp. In the northern section, the Conejos River meanders near the River Springs Ranger Station and Menkhaven Ranch, while the surrounding Rio Grande National Forest is crisscrossed by pack trails and jeep paths, reflecting a mid-century period of recreation and livestock management.
