Virgin River, photo by Harold Davis. View this image larger.

Looking up, the world is reduced to a crescent of sunlight between the cliff walls the river has carved over the eons of time.

Ahead, around the next bend, the river is a trail that you cannot lose. Follow upstream, clothing wet, water sloshing in your hiking boots, and who knows what you’ll find?
