UTAH is one cool place. The climate and geology combine to make an extraordinary landscape of sweeping slickrock, desolate dirtscapes and wonderful canyons. Exploring this stuff is called canyoneering, and ranges from civilized strolls through terrain suitable for small children to technical explorations requiring ropes, wetsuits and a short memory for the discomforts experienced last time out.
