The Chiricahuas were formed ten to fifteen million years ago, when tectonic plates spread and subducted, lifting up mountains and dropping valleys, while erosion formed the canyons and exposed the rock. The rock was then eroded by wind, rain, ice, and sun. And finally, lichen (the green that covers many rock faces), which contains a mild acid that eats into the rock, across the expanse of geologic time, forms these amazing structures.
