MI-101 From the Dedication: A passion for rocks, a passion for the mountains, a passion for trains, and a passion for sharing his love for the San Juan Mountain/San Luis Valley region with others: these passions drove Rob Benson to envision the annual Cumbres & Toltec Scenic Railroad Geology Train and thus create the exciting and fulfilling event that you will experience today. This guidebook honors Rob Benson and his vision and is dedicated in his memory. His enthusiasm and good nature will be missed but his legacy remains. This guidebook serves to share his passions with all who venture on the historic narrow-gauge ride through a fascinating slice of Colorado/New Mexico geologic history. ALL ABOARD!
