Lava Flow Trail

The Lava Flow Trail explores the base of Capulin Volcano, traversing the ancient basalt lava flows that poured from the cone and spread across the surrounding grassland during the eruption events that shaped this corner of northeastern New Mexico. The route winds through a striking landscape of broken black basalt slabs interspersed with pinon pine and juniper woodland, with the symmetrical cone of Capulin rising dramatically above throughout the walk. The contrast between the dark, jagged lava rock and the surrounding golden shortgrass prairie is visually compelling in any season. Interpretive signs along the trail explain how lava flows cool and fracture, and point out features including pressure ridges, spatter cones, and sections of exposed lava tube ceiling that have partially collapsed. The basalt is estimated to be between 56,000 and 62,000 years old for the older flows, while the main cone is far younger at approximately 800 years. Pronghorn antelope, mule deer, and wild turkey use the lava flow margins as habitat, and the open terrain makes wildlife sightings common. In spring the grasses and wildflowers growing between the lava blocks create a beautiful textural contrast. The loop is accessible and family-friendly, making it an excellent complement to the more demanding rim walk on the same visit to the monument.
