1980 Map of Rito Alto Peak

About this map

Rio Grande National Forest and San Isabel National Forest meet along the high spine of the Sangre de Cristo Range, where the county line separates Saguache and Custer. This 1980 survey documents a high-altitude landscape defined by steep basins like Kolkman Basin and Groundhog Basin, punctuated by formidable summits such as Rito Alto Peak and Venable Peak. The infrastructure is largely seasonal and industrial, featuring a network of primitive routes including the Jeep Trail and Cotton Creek Trail.
