About this map

Rio Grande National Forest dominates the western half of this terrain, where the high desert meets the rising mountains of Saguache County. The map captures a high-altitude drainage system defined by Carnero Creek and La Garita Creek, which descend toward the San Luis Valley floor. Local social landmarks are concentrated near the northeastern corner, notably the St John Ch and an adjacent Cem, alongside Arroyo Mogotas. Evidence of early agricultural and industrial infrastructure is visible in the Rio Grande Canal and a long Pipeline, while distinctive formations like Eagle Rock, Elephant Rocks, and the aptly named Hellgate canyon pass serve as significant landmarks. The presence of several Prospect sites and a lonely Grave suggest the transient but persistent human activity common to this high-country landscape during the mid-20th century.
