He adds that those areas are often covered by a delicate cryptobiotic crust that protects the desert from erosion, and for which a hole is anything but beneficial. I've seen four-wheelers grind their way up desert rock formations near Moab, Utah, where century-old cryptobiotic crust, made up of soil lichens, green algae, bacteria, and mosses, is as easily damaged and difficult to restore as alpine tundra.
