About this map

Sangre De Cristo mountains dominate this high-altitude survey, where the boundaries of Costilla, Huerfano, and Las Animas counties converge. The drainage patterns on this 1967 edition reveal the headwaters of several significant systems, including the North Fork Purgatorie River and Trinchera Creek. In the eastern portion, the San Isabel National Forest hosts seasonal recreation at sites like the Bear Lake Campground and Blue Lakes Campground, connected by the Indian Creek Trail (Pack).

Evidence of high-country mineral exploration appears near the summit of Trinchera Peak, where a Mine and various Prospects are recorded. The topographic detail captures the steep transition from the glacial Beccerro Basin to the high ridges of Teddys Peak and Cuatro Peak. Water features such as Wolf Lake and Rito Seco emphasize the alpine environment's role as a vital watershed for the surrounding southern Colorado basins.
