Vulcan

Vulcan is an extinct spatter cone in West Mesa that rises approximately 600 feet above the valley floor with visible caves and natural arches. These features were created by flank vents during earlier volcanic episodes that shaped the mountain.

The last eruption occurred roughly 150,000 years ago, leaving behind a solidified lava pool of gray basalt with columnar jointing visible in the crater. The cone formed during an early phase of volcanic activity in this region of Albuquerque.

From 1951 to 1973, students painted a large letter J on the eastern slope, giving it the local nickname J Volcano. This playful marking became part of the area's identity and remains well-known among residents.

The cone sits within Petroglyph National Monument at an elevation of about 6,033 feet, making it accessible for visitors at a moderate height. The surrounding area with its chain of volcanic vents is straightforward to explore and offers good views across the landscape.

The cone contains radial sinuous lava tubes ranging from about 8 to 20 inches in diameter that extend up to 300 feet on the northeast and northwest flanks. These tubes show clearly how molten material once flowed through the mountain.
