The Valles Caldera (or Jemez Caldera) is a 13.7-mile (22.0 km) wide volcanic caldera in the Jemez Mountains of northern New Mexico. [1] Hot springs , streams, fumaroles , natural gas seeps, and volcanic domes dot the caldera landscape. [ 4 ]
Although the Valles caldera is not unusually large, it is relatively young (1.25 million years old) and unusually well preserved, [31] and it remains one of the best studied examples of a resurgent caldera. [6] The ash flow tuffs of the Valles caldera, such as the Bandelier Tuff, were among the first to be thoroughly characterized. [32]
Redondo Peak (Tewa: Tsiku'mup'in) is a conspicuous summit in the Jemez Mountains of New Mexico, in the southwestern United States. [3] It is located entirely within the Valles Caldera National Preserve.
The formation is composed of ignimbrites produced by a series of at least three Quaternary caldera eruptions that culminated in the Valles Caldera eruption 1.256 million years before the present . [1] The Valles Caldera is the type location for resurgent caldera eruptions, [2] and the Bandelier Tuff was one of the earliest recognized ...
The caldera is segregated by these structures and its rim into multiple lush grass valleys (valles in Spanish, hence the name). The western part of the Valles Caldera is underlain by a seismic low-velocity zone with an area of 10 by 14 kilometers (6.2 by 8.7 mi) and extending to depths of 5 to 15.5 kilometers (3.1 to 9.6 mi). This zone consists ...
The Pajarito Plateau is a volcanic plateau in north central New Mexico, United States.The plateau, part of the Jemez Mountains, is bounded on the west by the Sierra de los Valles, the range forming the east rim of the Valles Caldera, and on the east by the Puye escarpment, which rises about 300 to 400 feet (90 to 100 m) above the Rio Grande valley about a mile (1.6 km) west of the river.
Spence Hot Springs are a group of geothermal springs located north of the town of Jemez Springs, New Mexico, in the Valles Caldera National Preserve. [1] [2] Features
The Tewa Group is a sequence of mostly rhyolite pyroclastic flows and domes that underlies much of the Valles Caldera and forms extensive outflow sheets surrounding the caldera. It has a maximum thickness of 1,050 m (3,440 ft).
