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 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.
