Diagram of the Yellowstone Caldera. The Lava Creek eruption of the Yellowstone Caldera, which occurred 640,000 years ago, [40] ejected approximately 1,000 cubic kilometres (240 cu mi) of rock, dust and volcanic ash into the atmosphere. [3] It was Yellowstone's third and most recent caldera-forming eruption.
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 caldera clearly visible today is the later Henry's Fork Caldera, which is the source of the Mesa Falls Tuff. It was formed 1.3 Ma in an eruption of more than 280 km 3 (67 cu mi). The two nested calderas share the same rim on their western sides, but the older Island Park Caldera is much larger and more oval and extends well into Yellowstone ...
The Greater Yellowstone Ecosystem (GYE) is one of the last remaining large, nearly intact ecosystems in the northern temperate zone of the Earth. [1] It is located within the northern Rocky Mountains , in areas of northwestern Wyoming , southwestern Montana , and eastern Idaho , and is about 22 million acres (89,000 km 2 ). [ 2 ]
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 ...
1 Shore length is not a well-defined measure. Yellowstone Lake is the largest body of water in Yellowstone National Park. The lake is 7,732 feet (2,357 m) above sea level and covers 136 square miles (350 km 2) with 110 miles (180 km) of shoreline. While the average depth of the lake is 139 ft (42 m), its greatest depth is at least 394 ft (120 m ...
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 ...
The geothermal areas of Yellowstone include several geyser basins in Yellowstone National Park as well as other geothermal features such as hot springs, mud pots, and fumaroles. The number of thermal features in Yellowstone is estimated at 10,000. [ 1 ] A study [ 2 ] that was completed in 2011 found that a total of 1,283 geysers have erupted in ...
