Some sites are found without searching, some will not be found no matter how long we search. Light conceals and then reveals it. Trees and brush hide it. Trails lead uphill and into the sun. It is usually either hot and dusty or cold and windy.

The ancient inhabitants of our world left rock art in the form of designs and images painted and pecked on boulders, cliffs and cave walls. In the United States, countless sites exist with rock art ranging from simple, solitary motifs to extensive galleries of figures and designs. The images range in age from 200 to 10,000 years and rock art styles classify rock art based on elements, techniques, geographic area and time period. Some scholars advise against interpreting rock art but most of us interpret everything we see and rock art is no exception. A petroglyph panel composed of animals and human figures with bows and arrows looks like a hunting scene.
