Bob Krantz resides in Durango, Colorado, where he combines geological teaching and research with telling non-specialists about earth history.

Bob is a consulting geologist, Adjunct Professor at the University of Arizona in Tucson and faculty member at Fort Lewis College in Durango. He specializes in fault and fracture systems, with current research focusing on applying 3-D cognitive and visualization skills in complex structural settings.

While a grad student in Tucson and throughout his career, Bob has led field trips for the general public, including for Elderhostels, many in his native Arizona. He has also engaged with K-12 educators for science enrichment, and is past chair of the AAPG Youth Education Activities committee.

Bob’s love of field geology has to accommodate his other interests. He has a passion for sports cars, from restorations to racing. Once a competitive mountain biker, he still enjoys riding trails around the west. And Bob still finds time to pursue landscape photography, with both digital and old-school film.
