Yellowstone Caldera, also known as the Yellowstone Plateau Volcanic Field, is a Quaternary caldera complex and volcanic plateau spanning parts of Wyoming, Idaho, and Montana. It is driven by the Yellowstone hotspot and is largely within Yellowstone National Park .
(See Yellowstone Caldera map.) The Henry's Fork Caldera in Idaho was formed in an eruption of more than 280 km 3 (67 cu mi) 1.3 million years ago, and is the source of the Mesa Falls Tuff. [11] The Henry's Fork Caldera is nested inside of the Island Park Caldera and the calderas share a rim on the western side.

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 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. [4] [5] It is a popular site for tourists. [6] Map of Yellowstone Volcano ash beds
The caldera is the enormous volcanic crater left from the last time Yellowstone experienced a giant eruption, 640,000 years ago. It covers an area about 30 by 45 miles .
The zircon and phenocrysts rims recorded that the magma of the Lava Creek Tuff was generated from a mix of mantle, Archean crust, and shallow hydrothermally altered intra-caldera rocks. Member A and B were sourced from separate magma reservoirs prior to eruption, [ 19 ] at a depth range of 3–6 km (1.9–3.7 mi) [ 20 ] and a temperature of 790 ...
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 Yellowstone, 465 of which are active during an average year. These are distributed among nine geyser basins, with a few geysers found in smaller thermal areas throughout the Park.
