Petroglyph National Monument

Petroglyph National Monument stretches 17 miles along Albuquerque, New Mexico's West Mesa, a volcanic basalt escarpment that dominates the city's western horizon. Authorized June 27, 1990, the 7,236 acres monument is cooperatively managed by the National Park Service and the City of Albuquerque. The western boundary of the monument features a chain of dormant fissure volcanoes. Beginning in the northwest corner, Butte volcano is followed to its south by Bond, Vulcan, Black and JA volcanoes.

Petroglyph National Monument protects a variety of cultural and natural resources including five volcanic cones, hundreds of archeological sites and an estimated 24,000 petroglyph images carved by Ancestral Pueblo peoples and early Spanish settlers. Many of the images are recognizable as animals, people, brands and crosses; others are more complex.
