JA Volcano is the southernmost of 5 volcanoes in a 5-mile chain within the western boundary of Petroglyph National Monument. Students from John Adams Middle School in Albuquerque constructed a rock JA image on the East side of the cone which they whitewashed annually. The J is still visible from the city. Directly north of JA is Black, followed by Vulcan, Bond and Butte volcanoes. The date of its last eruption is unknown, but is believed to have been more than 150,000 years ago. http://www.canyoncountryzephyr.com/wp-content/uploads/2014/11/LA10.jpg {{Commons category|JA Volcano}}{{NewMexico-geo-stub}} 5 : Volcanoes of New Mexico|Inactive volcanoes|Pleistocene volcanoes|Landforms of Bernalillo County, New Mexico|Stratovolcanoes of the United States |
