For millions of years, the Virgin River has been carving its way through layers of rock, forming the The Narrows Zion National Park. This canyon twists and turns for miles creating one of the most unique hiking trails in the world.
The canyon is so narrow the hike is basically walking up the Virgin River, which means that in many places, you have to wade or swim to proceed, all while walking on rounded river rocks.
I used this small tree as a reference point to put the sheer size of the canyon walls in perspective. Keith Peters
