About this map

Antonito and the surrounding high-altitude terrain of the San Juan Mountains define this mid-1980s landscape near the Colorado and New Mexico border. The map illustrates a region transitioning from the agricultural expanses of the San Luis Valley in the east to the high wilderness of the San Juan National Forest and Rio Grande National Forest to the west. A notable industrial and historical corridor is visible near the Conejos River, where small settlements like Mogote, Las Mesitas, and Paisaje follow the river's path.

Resource extraction and transit history are highlighted by the Black Diamond Mine and the high-elevation site at Summitville. The Cumbres and Toltec Scenic Railroad winds through the southern terrain, providing a look at the narrow-gauge infrastructure that once linked these mountain outposts. The network of water sources, including the Rio Grande River, Alamosa River, and Platoro Reservoir, anchors the scattered mountain communities and mining sites within the South San Juan Wilderness and Weminuche Wilderness.
