Valles Caldera (or Jemez Caldera) is a 13.7-mile (22.0 km) wide volcanic caldera in the Jemez Mountains of northern New Mexico. Hot springs, streams, fumaroles, natural gas seeps and volcanic domes dot the caldera floor landscape.[2] The highest point in the caldera is Redondo Peak, an 11,253-foot (3,430 m) resurgent lava dome located entirely within the caldera. Also within the caldera are several grass valleys [Valle(s)] the largest of which is Valle Grande (local pronunciation: /ˈvaɪ.eɪ ˈɡrɑːndeɪ/; VY-ay GRAHN-day), the only one accessible by a paved road. Much of the caldera is within the Valles Caldera National Preserve, a unit of the National Park System.
