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
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 .
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.
The Central Plateau separates the Hayden Valley and Yellowstone River drainage on the east from the Lower Geyser Basin and the Madison River drainage on the west. Madison Plateau 44°21′02″N 110°58′18″W / 44.35056°N 110.97167°W / 44.35056; -110.97167 ( Madison Plateau ) , [ 8 ] 8,435 feet (2,571
The hotspot's most recent caldera-forming supereruption, known as the Lava Creek Eruption, took place 640,000 years ago and created the Lava Creek Tuff, and the most recent Yellowstone Caldera. The Yellowstone hotspot is one of a few volcanic hotspots underlying the North American tectonic plate; another example is the Anahim hotspot.
This eruption of 2,450 km 3 (590 cu mi) of material is thought to be one of the largest known eruptions in the Yellowstone hotspot's history. This eruption, 2.1 million years ago, is the third most recent large caldera-forming eruption from the Yellowstone hotspot. It was followed by the Mesa Falls Tuff and the Lava Creek Tuff eruptions.

Spasmodic Geyser is a geyser located in the Upper Geyser Basin in Yellowstone National Park in the United States. Spasmodic Geyser's eruptions from the two craters can be up to 15 feet (4.6 m) high. Water can also erupt from a few inches to ten feet high from the approximately 20 vents.
The Mesa Falls Tuff is a tuff formation produced by the Mesa Falls eruption that formed the Henry's Fork Caldera that is located in Idaho west of Yellowstone National Park. [1] It is the second most recent caldera forming eruption from the Yellowstone hotspot and ejected of 280 km 3 (67 cu mi) of material.
