1985 Map of Antonito

About this map

The San Juan Mountains and the high desert of the San Luis Valley meet in this mid-1980s survey of the Colorado-New Mexico borderlands. The intricate route of the Cumbres and Toltec Scenic Railroad winds through the southern terrain, crossing Rio de los Pinos and Cumbres Creek near the state line. To the east, the landscape transitions from the peaks of the South Continental Divide San Juan Mountains Wilderness to the agricultural reaches near Antonito and Mogote. Historical extraction is evident at high elevations, with the Black Diamond Mine and Mammoth Revenue Mine located near Summitville. The map also captures several water management sites crucial to the region's ranching and recreation, including Platoro Reservoir, La Jara Reservoir, and Trujillo Meadows Reservoir.
