Finding petroglyphs (rock carvings) and pictographs (rock paintings) in the United States has never really been that hard. Petroglyph National Monument in Albuquerque boasts more than 25,000 images—mostly humans, animals and tribal symbols—carved into volcanic rocks by Native Americans and Spanish settlers 400 to 700 years ago, and another obvious site, Canyonlands National Park in southeastern Utah, is famously known for life-size human figures and depictions of men fighting, painted between 900 and 2,000 years ago.
