About this map

The Sangre De Cristo Range dominates this mid-1990s survey, marking a sharp topographic divide along the high ridges of Trinchera Peak and Teddys Peak. This alpine environment is defined by its dramatic elevation changes, where glacial features like Bear Lake, Blue Lakes, and Wolf Lake sit tucked beneath the peaks. The eastern slopes are home to the Cuchara Valley Ski Area, illustrating the 20th-century transition toward recreational land use within the San Isabel National Forest.

Evidence of earlier human activity appears near the high ridges, including a designated Mine and various Prospects in the southern reaches. The map also delineates the complex jurisdictional boundaries of the Grant Boundary and the converging corners of Costilla, Huerfano, and Las Animas counties. Drainage patterns on both sides of the divide are meticulously charted, from the Trinchera Creek headwaters in the west to the North Fork Purgatoire River in the southeast.
