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 .
Map showing extent of ashfall from eruptions. The Yellowstone Caldera formed over 600,000 years ago from ... The National Park Service said the eruption covered an area just shy of the size of ...
The Island Park Caldera is sometimes referred to as the First Phase Yellowstone Caldera or the Huckleberry Ridge Caldera. The youngest of the hotspot calderas, the Yellowstone Caldera, formed 640,000 years ago and is about 34 miles (55 km) by 45 miles (72 km) wide.
The Yellowstone Caldera has two resurgent domes formed by magma upwelling called Sour Creek and Mallard Lakes. [8] The magma chambers under the Yellowstone Caldera provides heat and energy for large hydrothermal systems. [8] [9] The Yellowstone Caldera has the greatest concentration of hydrothermal features in the world, and is an active system ...
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 .

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 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 ...
