About this map

The San Juan National Forest defines the rugged borderlands of Colorado and New Mexico in this mid-century survey. The landscape is a high-altitude mix of named mesas and deep canyons, where the Navajo River and Rio Blanco provide the primary drainage. The settlement of Edith sits near the southern boundary, positioned within the expansive Tierra Amarilla Grant.

Resource extraction and land management are evident through markers like the Squaretop Guard Station and scattered Oil Wells. For genealogists and local historians, family-named landmarks such as Kenney Flats, Cornish Hill, and Cornish Gulch suggest early ranching or homesteading footprints. The map also records numerous high-country water sources, including Buckles Lake and Harris Lake, which were likely critical for both the forest service and local stockmen during this era.
