Huell travels to the Naval Air Weapons Station China Lake to see the largest concentration of rock art in the Western Hemisphere. The small canyon houses up to 6,000 images. Although an accurate dating technique is still being sought, certain petroglyphs are thought to be 16,000 years old, while others were made as recently as 1800. This rock art is so important to our cultural heritage and our knowledge of the desert's past that the sites were listed in the National Register of Historic Places in 1964.
