The Virgin River is a tributary of the Colorado River in the U.S. states of Utah, Nevada, and Arizona.
The river is about 162 miles long. It was designated Utah's first wild and scenic river in 2009, during the centennial celebration of Zion National Park.
While it looks meek and mild in this photo, the danger of flash flooding in the narrow canyon is very real and very dangerous.
Just a couple inches of rain can create a 55 foot wall of water in minutes.
