The Dotsero Crater in western Eagle County, is Colorado’s only active volcano. A new report from the United States Geological Survey lists it as a moderate threat to human activity. Don’t worry, Dotsero is not expected to erupt again anytime soon, but it does give us a chance to explore the report, and this mysterious piece of Colorado geology a little further. To help with the details, 9NEWS turned to Richard Busch with the Denver Museum of Nature and Science. He is an archeologist by expertise, but as an educator with the museum, he must be well versed in everything from anthropology to zoology.
