People who have lived in New Mexico for thousands of years live on through images they carved into the shiny black volcanic rock. These images are from the Three Rivers Petroglyph National Recreation Site, north of Alamogordo. More than 21,000 glyphs of birds, humans, animals, fish, insects and plants, as well as numerous geometric and abstract designs are scattered over 50 acres of the Tularosa Basin. The Jornada Mogollon people created these petroglyphs about 1,000 years ago.
