The Sky Rock Petroglyphs were carved into the ancient volcanic tablelands near Bishop, California.
Their age and history are undetermined, but they are believed to be as old as 1,000 years.
Chipped into the dark desert rock in the shadow of the Sierra Nevada Range, the lighter rock beneath was exposed creating the glyphs.
While it is unknown who exactly created the Sky Rock glyphs, it is believed that the ancient ancestors of Shoshone-Paiute native people were responsible.
