JA Volcano is an inactive volcano located near Albuquerque, New Mexico. JA Volcano is the southernmost of 5 volcanoes in a 5-mile chain within the western boundary of Petroglyph National Monument.The volcano has been the site of repeated pranks: "Volcano “Erupts” But Fools No One—a 1950 newspaper headline declared. Nobody was fooled, apparently, because the same prank—piling tires on the side of a volcano and setting them on fire to simulate an eruption—had been tried in 1947 with much greater success (even causing a panic in the city). For years students from nearby St Joseph would paint a "J" on Vulcan Volcano, when the light is right it can still be seen." St. Joseph College was later named the University of Albuquerque. In 1950 the College of St. Joseph began its move into a newly built campus on the palisades along the Rio Grande below the volcano. The name was changed to the College of St. Joseph on the Rio Grande. In 1966, the institution changed its name again to the University of Albuquerque. Twenty years later, it closed its doors and became the campus of Pius X high school. The volcano is composed of a type of volcanic rock called olivine tholeiitic basalt. Radiometric dating indicates an age for this rock of about 156,000 years. The volcano consists of two flows with a spatter cone at the center. Late in the eruption, subterranean pressure bulged the surface beneath the cone, causing radial cracking that resulted in emplacement of dikes around the cone. A final explosion blew out the eastern rim of the cone.

Petroglyph National Monument
Petroglyph National Monument

Petroglyph National Monument stretches 17 miles (27 km) 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 (2,928 ha) 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. Their meaning was, possibly, understood only by the carver. These images are the cultural heritage of a people who have long since moved into other areas and moved on through history for many reasons. The monument is intended as a protection for these lands and sites from and for visitors to see and appreciate for generations to come. The national monument is managed in a manner that allows recreational use. The monument has four major sites that visitors can access, Boca Negra Canyon, Rinconada Canyon, Piedras Marcadas Canyon, and the Volcano Day Use trails.
