The Albuquerque volcanic field is a monogenetic volcanic field in the Albuquerque Basin in New Mexico, United States. It is located about 7 miles (11 km) west of the city of Albuquerque, and is contained within the borders of Petroglyph National Monument.[1] The field was active from 190,000 to 155,000 years ago[2] and includes lava flows, cinder cones, and spatter cones.[1] The oldest lava flows cover about 23 square miles (60 km2). The cones are aligned and possibly formed above two roughly north-south trending fissures.[3] Vulcan (also called J Volcano) is the highest feature. Its base is made of cinder, but the crater contains a lava dome that was cut by an explosive eruption.[2]
