1973 Map of Columbine Pass

About this map

High-altitude mining claims and alpine reservoirs define this 1970s landscape within the San Juan National Forest. The rugged topography is dotted with historical mineral interests, most notably the Pittsburg Mine and several other unnamed mines clustered near Columbine Pass and Vallecito Basin. These sites are linked by the Needle Creek Trail and various pack trails, suggesting a period when access was primarily limited to foot or horse. Water management for the region is evident in the complex of reservoirs serving nearby communities, including City Reservoir, Castilleja Lake, and Lillie Lake. The former location of Logtown sits near the Florida River, providing a focal point for those researching the vanished settlements of La Plata County. Prominent peaks like Mount Eolus and Windom Peak dominate the skyline above the alpine Chicago Creek.
