Few experiences compare to standing at the edge of ancient volcanic history with someone who can bring it to life. Harvey DuChene, a local geologist with deep knowledge of the region, leads this half-day driving tour through some of the most geologically significant viewpoints in the Lake City area. From dramatic overlooks to sweeping valley vistas, each stop reveals a new chapter in the volcanic story of this remarkable corner of Colorado.
The tour is largely vehicle-based with minimal walking, making it accessible to a wide range of participants. Carpooling is strongly encouraged as vehicles are not provided, and participants are asked to come prepared for a morning outdoors — bring a folding camp chair, drinking water, a hat, a jacket, sunscreen, and a snack.
