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]
Valles caldera is located in north-central New Mexico in the central Jemez Mountains west of Santa Fe. It is the oldest of three young caldera-type volcanoes in the United States; the other two are Yellowstone in Wyoming and Long Valley in California.
The Valles Caldera is a supervolcano eruption, like Yellowstone, and one of the largest young calderas on Earth. It formed about 1 million years ago when multiple explosive eruptions occurred that produced an immense outpouring of ash, pumice, and pyroclastic flows.
21 cze 2024 · About 1.2 million years ago, a spectacular volcanic eruption created a 14-mile-wide circular depression in the earth now known as Valles Caldera. The preserve is known for its huge mountain meadows, abundant wildlife, and meandering streams.
7 kwi 2021 · In the heart of northern New Mexico sits the over 20-kilometer-wide depression known as the Valles Caldera. Within and around this caldera are clear remnants of the massive volcanic eruption that created this depression, such as unusual rock formations and thermal springs.
The Valles caldera exhibits world-class examples of the landforms produced by a very large, explosive volcano, and the preservation and exposure of geological features within the Valles is spectacular.
29 maj 2023 · Yellowstone National Park is well known for its geysers and hot springs. While such activity is not as prominent at Valles Caldera, there is a noteworthy hydrothermal area, called Sulphur Springs, that is similar to the acid-sulfate thermal areas in Yellowstone, like the Mud Volcano region.
