Fodor's Expert Review Petroglyph Canyons
Thousands of well-preserved images of animals and humans are scratched or pecked into dark basaltic rocks at Big Petroglyph and Little Petroglyph canyons in the Coso Mountain range, the largest concentration of ancient rock art in the Northern Hemisphere. The canyons lie within the million-acre U.S. Naval Weapons Center at China Lake. Only the drawings of Little Petroglyph can be visited, and only on a guided tour arranged in advance through the Maturango Museum. Tour participants must be U.S. citizens over 10 years of age, and fill out an online application to obtain security clearance. Detailed information about the spring and fall tours, which fill up fast, is provided on the museum's website.
