Some canyons of Zion National Park are domated by a living soil called Cryptobiotic Crust, which contains lichen and mosses, and bacteria. This crust provides a stable foundation for plants and mosses to grow, which otherwise would have difficuly enduring the winds and rainstorms in the shifting sand. The soil is very delicate and a single foot print can damage it. If you're hiking and come across this soil, walk around it!
