The mission of the Colorado Geological Survey is building vibrant economies and sustainable communities, free from geologic hazards, for people to live, work and play through good science, collaboration, and sound management of mineral, energy and water resources. Vision of the Colorado Geological Survey: Protect public safety and enhance the economy of Colorado. The Colorado Geological Survey (CGS) goals are to help reduce the impact of geologic hazards on the citizens of Colorado, to promote the responsible economic development of mineral and energy resources, to provide avalanche safety training and forecasting, to provide geologic insight into water resources, and to provide geologic advice and information to a variety of constituencies.The ancient basement rocks of southern Colorado were formed during Proterozoic orogenies, mostly in the middle Proterozoic, 1.0 to 1.8 billion years ago. A great variety of granites and metamorphic rocks make up the Proterozoic crust.

Huerfano County has been described as "a broken, tilted and eroded plateau bridging the mountains and the high plains." Most of the tilting we see today occurred about 27 million years ago, during the Sangre de Cristo upthrust.
About 36 million years ago, there was a catastophic volcanic eruption near Mt. Princeton in the Collegiate Range, about 100 miles to the west. The eruption created a superheated cloud of pumice, ash, and rock that traveled to this area within about an hour.

Oh the buzzin' of the bees in the cigarette trees Near the soda water fountain At the lemonade springs where the bluebird sings On the big rock candy mountain Do you remember the late Burl Ives singing that old 1930s hobo song, dreaming of a mountain made of sugar, where life was easy and work unknown?
Huerfano County has been described as "a broken, tilted and eroded plateau bridging the mountains and the high plains." Most of the tilting we see today occurred about 27 million years ago, during the Sangre de Cristo upthrust. That tilted the county higher in the west and it was the generally easterly flow of runoff that has caused the surface erosion we see now.
