The Yellowstone Caldera, sometimes referred to as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States. The caldera and most of the park are located in the northwest corner of the state of Wyoming. The caldera measures 43 by 28 miles (70 by 45 kilometers), and postcaldera ...
44°26′N 110°40′W / 44.43°N 110.67°W / 44.43; -110.67. The Yellowstone hotspot is a volcanic hotspot in the United States responsible for large scale volcanism in Idaho, Montana, Nevada, Oregon, and Wyoming, formed as the North American tectonic plate moved over it. It formed the eastern Snake River Plain through a succession ...
The Island Park Caldera, in the U.S. states of Idaho and Wyoming, is one of the world's largest calderas, with approximate dimensions of 80 by 65 km. Its ashfall is the source of the Huckleberry Ridge Tuff that is found from southern California to the Mississippi River near St. Louis. This super-eruption of approximately 2,500 km 3 (600 cu mi ...
Map of Yellowstone Volcano ash beds. The plateau developed through three volcanic cycles spanning two million years that included some of the world's largest known eruptions. The eruption of the >2,500 km 2 (970 sq mi) Huckleberry Ridge Tuff about 2 million years ago created the more than 75 km (47 mi) long Island Park Caldera.
The caldera — a 50-mile-wide volcanic crater — is the remnant of a pair of massive volcanic eruptions thrown up by the Yellowstone hotspot as it wandered east to its current location. At its ...
Yellowstone National Park spans an area of 3,468.4 sq mi (8,983 km 2), [3] with lakes, canyons, rivers, and mountain ranges. [11] Yellowstone Lake is one of the largest high-elevation lakes in North America and is centered over the Yellowstone Caldera, the largest super volcano on the continent. The caldera is considered a dormant volcano.
Lava Creek Tuff. The Lava Creek Tuff is a voluminous sheet of ash-flow tuff located in Wyoming, Montana and Idaho, United States. It was created during the Lava Creek eruption around 630,000 years ago, which led to the formation of the Yellowstone Caldera. This eruption is considered the climactic event of Yellowstone's third volcanic cycle.
The Huckleberry Ridge Tuff is a tuff formation created by the Huckleberry Ridge eruption that formed the Island Park Caldera that lies partially in Yellowstone National Park, Wyoming and stretches westward into Idaho into a region known as Island Park. [2] This eruption of 2,450 km 3 (590 cu mi) of material is thought to be one of the largest ...
