About this map

Trinchera Peak anchors this high-elevation corner of the Sangre de Cristo Mountains in southern Colorado, where the headwaters of several major regional drainages begin. The topography is defined by sharp ridgelines and deep glacial carvings, including Beccerro Basin and Big Meadow. These alpine environments serve as a primary water source, feeding Trinchera Creek to the west and the North Fork Purgatoire River and Cucharas Creek to the east.

Recreational development is centered in the northeastern portion of the sheet, where the Cuchara Valley Ski Area and various alpine waters like Bear Lake and Blue Lakes provide focal points for seasonal activity. Tracing the transition from peak to valley, the map shows a network of canyons such as Deep Canyon and Apache Canyon, illustrating the complex geological erosion of the Culebra Range. This 2011 survey captures the area at a time when traditional high-country recreation and watershed management remained the primary human imprints on the landscape.
