As a geologist, author and guide, I love to share my appreciation of earth history with anyone who is curious about landscapes and how they may have formed. I have a passion for landscapes and how cultures either thrived or withered because of those landscapes. I also love foreign travel, ancient peoples and hiking in the great outdoors.

My association with high quality educational organizations such as the Museum of Northern Arizona, Grand Canyon Field Institute, Coconino Community College, Smithsonian Journeys, and TCS Expeditions means that no matter where we might travel together, we will learn about and enjoy the varied beauties of this planet.

On October 6, 2007, my book, "Carving Grand Canyon" received a prestigious Glyph Award in the category of Best Science Book, Arizona–2007! Glyph Awards are the Arizona equivalent of a National Book Award. The award ceremony was held at the Phoenix Country Club and was hosted by the Arizona Book Publishers Association. Voting was conducted among various Arizona librarians and book publishers. I was traveling in Nepal at the time of the award, which was accepted on my behalf by Kathryn Conrad of the University of Arizona Press. Read all about it!
