After escaping Rattlesnake Canyon, we made a beeline for the San Rafael Swell in Utah, a region that is a labyrinth of canyons within ancient rock. I experienced one canyon on my bike from its rim and its depths. First, I rode along its canyon wall and peered down at the dizzying view. A day later, I rode along the riverside down on the canyon floor (details tomorrow). That canyon was called "Little Grand Canyon". The San Rafael River courses through it.
