Yellowstone Plateau Volcanic Field

About

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. The Yellowstone Plateau Volcanic Field began forming around 2 Ma (million years ago). It has had over 110 different eruptions and has created mostly rhyolitic plains, with over 6000 km3 of rhyolitic material formed. Scientists have discovered three major eruptions that formed calderas. They used methods of geological mapping, with both satellites and field work, and potassium-argon dating, to discover the eruptions. The three major eruptions are: The first large eruption was about 2.08 Ma and created the Huckleberry Ridge Caldera. This eruption produced more than 2,500 km2 of magma through at least three volcanic vents that produced large ash sheets across the area. This caldera had three main pulses of activity during its formation. The second large eruption was about 1.3 Ma and created the Henrys Fork Caldera. This eruption produced more than 280 km2 of magma and was nested within a portion of a larger caldera, the Huckleberry Ridge Caldera. The third large eruption was about 0.6 Ma and created the Yellowstone Caldera. This eruption produced 1,000 km2 of magma through at lea
