Stephen Darveau

rock climbing zion

Stephen is a Utah local who was born and raised in SLC, and is currently living in Virgin, UT. His parents were very active all the time and his mother was a professional aerial and mogul skier.  Stephen’s first guide gig was guiding snowmobile tours near Park City UT. As much as he loved it (saved his life after the death of his first son Gabriel) Stephen quickly realized that lifting those heavy machines out of the snow all day was a just temporary job. On the other hand, rock climbing and canyoning have been known to save his soul. Stephen has been climbing for over a decade and guiding rock climbing and canyons in Southern Utah for about 6 years now. Showing people the parallels that these activities have with life are his passion. Stephen has two children, Lykan and Olive. They are both climbers (on some days better climbers than their dad.) During the last 6 years Stephen has incorporated rock climbing and canyoneering into a few different residential treatment centers around town. The therapeutic value has had a great deal of influence on many lives including his own. It is Stephen’s hope to maybe share some of this experience with the guests of Rock Odysseys.

Mark has been calling Utah home since 2000, and currently lives in Santa Clara. He has been a Registered Nurse since 2008, and currently works in the Intensive Care Unit at Dixie Regional Medical Center in Saint George with a Critical Care Registered Nurse (CCRN) certification. He is married with two boys, ages 2 and 4. Mark is passionate about the outdoors, and savors the time he has away from his “real job” to pursue his passion of rock climbing. He has developed several routes in the Southwest and some of his proudest contributions include “The Undeniable Lightness of Being Lyle” and “Legends Never Die” in Snow Canyon State Park, along with several big wall adventure routes in Kayenta, UT.

Zion National Park is uniquely beautiful, and attracts and enchants people from all over the world. Some are content to look up and walk the established trails and byways, but others are compelled to know Zion and the surrounding untamed backcountry more intimately. They rappel into hidden, water-carved canyons and climb the rock face to experience a rarer, more intricate view or vista. It gets in their blood, and some devote their lives to the rush and to the beauty.
Our guides are these kinds of explorers; they have a genuine love of the area, as well as for their craft, and are guaranteed always to be technically superior and professional.
