About this map

Trinchera Peak rises as a central landmark at the tri-county junction of Costilla, Huerfano, and Las Animas, where the high ridges of the Sangre De Cristo Range dominate the landscape. This 1967 survey, updated with 1982 revisions, reveals a high-altitude wilderness defined by glacial features and steep drainage basins. East of the divide, within the San Isabel National Forest, the headwaters of the North Fork Purgatoire River and Cucharas Creek emerge from alpine catchments like Blue Lakes and Wolf Lake.

Evidence of resource exploration appears near the southern peaks, where a Mine and various Prospects are noted above Hells Canyon. The western slopes are characterized by long, descending drainages such as Squirrel Canyon and Trinchera Creek, which flow toward the San Luis Valley. This topography highlights the area's isolation, accessible primarily by the Indian Creek Trail (Pack) and scattered jeep tracks, preserving the character of the Colorado high country before modern development reached these summits.
