El Malpais National Monument in western New Mexico preserves a stark volcanic landscape within the Zuni-Bandera volcanic field, where black lava flows, cinder cones, lava tubes, and ice caves spread across a rugged basin. Its geology includes the Grants Lava Flows, Bandera Crater, El Calderon, and the Chain of Craters, while caves such as Giant Ice, Lava Bomb, and Junction Bridge create unusual habitats for bats and rare plants. Indigenous peoples used this harsh terrain for centuries, including a trail linking Acoma and Zuni communities. Established in 1987, the monument also reflects tensions over spiritually important land and remains significant for both natural and cultural history.
