Three miles east of here, along a mile-long volcanic ridge, is one of the most concentrated arrays of petroglyphs in the Southwest, with some 21,000 images of animals, humans, plants, and geometric shapes and public access to an unusually large number of examples of rock art. The Jornada Mogollon people etched the glyphs into dense basalt rock with stone tools circa 900-1400 A.D., and Sierra Blanca Peak towers above the site.
