Petroglyph National Monument

Petroglyph National Monument on the western edge of Albuquerque, New Mexico, protects approximately 24,000 images carved into the dark basalt boulders of a 17-mile volcanic escarpment by ancestral Puebloans and early Spanish settlers over the past 700 years. The monument encompasses five distinct areas, three of which are open to the public: Boca Negra Canyon, Rinconada Canyon, and Piedras Marcadas Canyon. Boca Negra Canyon is the most visitor-friendly unit, with three short trails (0.2 to 0.4 miles each) leading past dense concentrations of carvings on paved surfaces. Common motifs include spirals, masks, serpents, bird figures, human hand prints, and abstract symbols that continue to hold religious and cultural significance for contemporary Pueblo communities, who regard the escarpment as sacred. Rinconada Canyon offers a 2.2-mile round-trip unpaved trail along the base of the escarpment with more dispersed but often more dramatic carvings in a far quieter setting than Boca Negra. The visitor center on Unser Blvd NW provides context through a brief interpretive film and exhibits covering petroglyph production, the ancestral Puebloan culture of the Albuquerque basin, and ongoing threats to the monument from residential development along its boundaries. Three Spanish colonial crosses carved by early settlers are visible in Boca Negra Canyon alongside older Puebloan images, illustrating the layered historical significance of the basalt escarpment. At 17 miles long, the monument preserves more petroglyphs per linear mile than any comparable site in New Mexico.
