Welcome To Tensleep Canyon Climbing. We take seriously the health and safety of those around the canyon. Be safe and have fun, but remember that even the best of circumstances can lead to danger. 

Our 11th edition guidebook is the continuation of the Aaron Huey guide and is published and distributed by The Tensleep Canyon Aerospace Society (TCAS), a collective that he established and immediately set free. 

TCAS is a group committed to the canyon itself, the walls and grass and water itself, nothing beyond that. We believe in calling out chipped holds. We believe in limited trail networks to climbing. We believe in picking up our trash as well as any trash we see. We believe  in donating all profits from guidebook sales as a matter of principle.
