About this map

Hellgate and Shaw Springs anchor the drainage basins of the Rio Grande National Forest in this 1960s study of Saguache County. The landscape is defined by the carved paths of Carnero Creek and La Garita Creek, where the terrain rises toward distinctive high points like Eagle Rock and the Elephant Rocks. These geological formations, along with numerous unnamed springs, dictated the placement of early infrastructure, from the Ancha Trail to more modern developments such as a major Pipeline and Canal system.

Evidence of early Colorado mountain life is found in isolated sites like St John Ch, a lone Cem, and a solitary marked Grave. The map records a transition from traditional resource extraction, seen at several marked Prospect sites, toward managed water systems as evidenced by the Gaging Sta along the creek banks. This survey provides a precise record of the remote intersections where mountain trails met the developing ranching and utility corridors of the mid-century West.
