The Dirt is Alive!:

If you look closely, you can see a microscopic community of life in the soil. Dark, lumpy surfaces are mature biological soil crust: a mixture of cyanobacteria, mosses, lichens, fungi, and algae. Young, living soil looks a lot like sand, and it needs to be left undisturbed for many years to mature and help plants grow. Just one footprint does years of damage. Dark, mature soil crusts are the basis of life in this desert. One footprint destroys years of growth. This remarkable soil community holds the sand together, absorbs moisture, produces critical nutrients for plants, and provides seed beds for new plants to take hold.

Please don’t walk on it. Stay on designated trails to protect living soil and plants.
