Two canyons in the Coso Mountain range, commonly called Big Petroglyph and Little Petroglyph, hold a superlative concentration of ancient rock art, the largest of its kind in the Northern Hemisphere. Thousands of well-preserved images of animals and humans are scratched or pecked into dark basaltic rocks. 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 must supply birthdate, birthplace, and Social Security information before visiting. Upon arrival, valid ID must be presented, along with vehicle registration and proof of insurance.
