Zion is the one, true Jurassic Park.Not much rain or snow falls here, but water has shaped the landscape.The red is rust--oxidized iron.
The sandstone of the Navajo formation dates back to dinosaur times.
Snow melt from the plateau top emerges at the bottom of the porous sandstone.Springs at the base of the cliffs undermine the towering walls.
Massive avalanches in the past have dammed the canyons.
The stream now cuts through lake deposits laid down behind one of those vanished dams.
