Fraser and Cathy Goff are PEEC volunteers that lead geologic tours through the Valles Caldera. The Valles is one of three active calderas in the mainland United States and the hot magma is only three miles below your feet when standing in the Valle Grande. Fraser Goff, retired geologist for LANL and adjunct professor at UNM, has been working on the Preserve for many years and has authored numerous books and papers dealing with the geology of the caldera. With the help of his geologist wife, Cathy Goff (retired from US Geological Survey), he conducts fact-filled tours of the east and central parts of the Preserve and provides thought-provoking answers to the public’s curiosity about this wonderful landscape. We hope you enjoy learning more about volunteers, Fraser and Cathy Goff.
