I am David Engel, I've been rock climbing and cave exploring since 1971 and exploring canyons for a number of years too. I am the organizer for a 3500 member (As of 8/2022) outdoor adventure group in the San Francisco Bay area. Helping people learn about outdoor adventures, our beautiful planet and communicating environmentally friendly and safe ways to explore is what I love to do.
