1980 Map of Rito Alto Peak

About this map

The high peaks of the Sangre de Cristo Mountains form a dramatic divide in this 1980 survey, where the boundary between Rio Grande National Forest and San Isabel National Forest follows the ridgeline. This terrain is defined by extreme elevations, spanning from Venable Peak and Rito Alto Peak down to the high-altitude basins of Kolkman Basin and Groundhog Basin. Local infrastructure reflects a history of both industry and transit, evidenced by numerous Mine and Prospect sites, as well as an Old Railroad Grade traversing the lower slopes. High alpine lakes like Cherry Lake and San Isabel Lake dot the landscape, connected by a network of primitive routes including the Cotton Creek Trail and Jeep Trail. On the southern edge, the Crestone Cem and North Crestone Campground provide evidence of nearby settlement and recreation at the mountain base.
