Petroglyph National Monument

Petroglyph National Monument is a relatively new park unit— established in 1990. Its purpose is to protect a large concentration of petroglyphs, as well as other cultural and natural resources, on the western edge of Albuquerque. Within the city limits, the three units of the monument are jointly owned and managed by the National Park Service, the State of New Mexico, and the City of Albuquerque. Native Americans and early European settlers created the petroglyphs on volcanic basalt boulders. The majority of the petroglyphs are Rio Grande Style from the Pueblo IV period, although some are attributed to Ancestral Puebloans and Desert Archaic people. The oldest images are thought to be 2,000-3,000 years old.
