1967 Map of Blanca Peak

About this map

San Isabel National Forest and Rio Grande National Forest converge on this high-altitude landscape, where the Sangre de Cristo range rises to its highest elevations. Surveyed in the late 1960s, the terrain is defined by massive peaks including Blanca Peak and Mount Lindsey, separated by deep glacial basins like Blanca Basin. Evidence of early mountaineering and resource extraction is visible through numerous prospects, a mine near Blanca Creek, and the presence of a Pack Trail winding toward Crater Lake. The lower elevations reveal the San Luis Valley Grant Bdy and the Arrowhead Ranch near Ikee Creek, indicating the transition from private ranching lands to protected federal forests. Water sources such as the Huerfano River and Ute Creek drain these alpine heights, linked by historic routes like the Ute Trail (Pack).
