About this map

Rio Grande National Forest dominates this 1967 survey of Saguache County, where the high-altitude landscape is defined by rugged summits and a network of traditional trails. The Twin Mountains and Eagle Mountain anchor the central terrain, which is intersected by a historical Stock Driveway and several primitive routes like the Pack Trail and Jeep Trail. Evidence of seasonal ranching and land use appears at the La Garita Corral in the north, while the presence of Prospects in the south suggests early mineral exploration within the high valleys.

Water sources are vital markers in this arid environment, with named features such as Usevia Springs, Ridge Spring, and Sunday Spring providing essential waypoints for travelers. Notable geological landmarks include the Natural Arch on the eastern edge and the winding descent of Old Woman Creek. The map meticulously details the transition from the peaks of Blue Mountain to the lower reaches of English Valley, capturing a snapshot of the region's wilderness character during the mid-20th century.
