Valles Caldera (or Jemez Caldera) is a 12 mi (19 km) wide volcanic caldera in the Jemez Mountains of northern New Mexico. It is one of only six known land-based supervolcanoes. The highest point in the caldera is Redondo Peak, an 11,258 foot resurgent lava dome located entirely within the caldera. Also within the caldera, Valle Grande ( /ˈvaɪ.eɪ ˈɡrɑːndeɪ/; VY-ay GRAHN-day) is the largest valle in the park and the only one with a paved road.
