Upper Black Box
San Rafael Swell
Technical Canyoneering

The Upper Black Box is a spectacular canyon. The San Rafael River has carved a deep narrow slot canyon into the heart of the San Rafael Swell. The Coconino sandstone walls are 400 feet high and in places only 25 feet wide. Canyoneering this route involves several miles of wading and swimming. Getting through the Upper Black Box is an exciting and entertaining adventure.

The San Rafael Swell is one of the most primitive and rugged areas in the lower 48 states. This also means that you must be self-reliant, plan ahead and use good judgment. Emergency Service, help or rescue is not close by or easily obtained. The Black Box can be deadly and should be taken seriously.
