Geology Underfoot in Southern Utah explores the stories behind 33 handpicked sites—some world—famous, others off the beaten path. Marvel at tales of ancient eruptions, deserts, seas, and swamps; the movements of massive rock units over eons; and the rock's interactions with the life above it, including humankind.

The authors include sites in Zion National Park, Natural Bridges National Monument, Bryce Canyon National Park, Canyonlands National Park, Arches National Park, Coral Pink Sand Dunes State Park, Escalante State Park, Fremont Indian State Park, the La Sal Mountains, and many more.
