Valles Caldera (or Jemez Caldera) is a 13.7-mile (22.0 km) wide volcanic caldera in the Jemez Mountains of northern New Mexico created by spectacular volcanic eruption of the Southwest's supervolcano about 1.25 million years ago. Hot springs, streams, fumaroles, natural gas seeps and volcanic domes dot the caldera floor landscape. 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, 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. The preserve is known for its huge mountain meadows, abundant wildlife, and meandering streams. https://en.m.wikipedia.org/wiki/Valles_Caldera http://www.nps.gov/vall/index.htm
