1965 Map of Twin Peaks

About this map

The high-elevation transition from the San Luis Valley floor to the jagged heights of the Sangre De Cristo Range is captured here during the mid-1960s. The landscape is defined by the steep drainage basins of the Rio Grande National Forest, where alpine features like Lake Como, Little Bear Lake, and the Blue Lakes sit thousands of feet above the valley floor. Water management is a central theme of the lower elevations, evidenced by the Garland Ditch, Holbrook Creek Dam, and scattered infrastructure such as the Tobin Creek Well and Mt Blanca Well.
