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 ...
The Lava Creek Tuff covers an area of more than 7,500 km 2 (2,900 sq mi) centered around the caldera and has an estimated magma volume of 1,000 km 3 (240 cu mi). The fallout from the eruption blanketed much of North America, depositing as one of the most widespread air-fall pyroclastic layers, formerly known as the Pearlette type O ash bed in ...
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 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 magma chamber that lies under Yellowstone is estimated to be a single connected chamber, about 37 miles (60 km) long, 18 miles (29 km) wide, and 3 to 7 miles (4.8 to 11.3 km) deep. [85] The current caldera was created by a cataclysmic eruption that occurred 640,000 years ago, which released more than 240 cu mi (1,000 km 3 ) of ash, rock and ...
The resulting 13 ft (4.0 m) river depth temporarily closed the busy channel to ocean-going freighters, costing Portland, Oregon, an estimated $5 million (equivalent to $15.5 million 2023). [43] Ultimately, more than 65 × 10 ^ 6 cu yd (50 × 10 ^ 6 m 3 ; 1.8 × 10 ^ 9 cu ft) of sediment were dumped along the lower Cowlitz and Columbia Rivers.
6,735 feet (2,053 m) [ 1 ] Type. Hot spring complex. Mammoth Hot Springs is a large complex of hot springs on a hill of travertine in Yellowstone National Park adjacent to Fort Yellowstone and the Mammoth Hot Springs Historic District. [ 3 ] It was created over thousands of years as hot water from the spring cooled and deposited calcium ...
The Yellowstone Plateau Volcanic Field, also known as the Yellowstone Supervolcano or the Yellowstone Volcano, is a complex volcano, volcanic plateau and volcanic field located mostly in the western U.S. state of Wyoming, but it also stretches into Idaho and Montana. It is a popular site for tourists. Map of Yellowstone Volcano ash beds
