2019 Map of Trinchera Peak

About this map

Trinchera Peak stands as the dominant sentinel at the intersection of Huerfano, Costilla, and Las Animas counties, anchoring a high-altitude landscape defined by the drainage divide between the Purgatoire and Cucharas river systems. Within the San Isabel National Forest, the topography transitions from the steep grades of Deep Canyon and Apache Canyon to subalpine basins such as Beccerro Basin. The 2019 survey delineates the intricate headwaters of the N Fork Purgatoire River and Hill Br Cucharas River, showing how water moves through high-mountain features like Blue Lakes and Wolf Lake. Land management boundaries are carefully noted, including the convergence of several townships such as t31s r70w and t31s r69w. The map provides a precise view of the remote corridors used for forest access, including Doyle Rd and the high-elevation Blue Bear Road (Snow).
