Webb9 juli 2024 · Subsequent flows of sticky rhyolite lava, the youngest of which erupted 70,000 years ago, filled Yellowstone caldera, obscuring the presence of the crater. The three large eruptions from the Yellowstone system respectively, were 2,500, 280, and 1,000 times larger than the 1980 eruption of Mount St. Helens in Washington state. Although the McDermitt volcanic field on the Nevada–Oregon border is frequently shown as the site of the initial impingement of the Yellowstone Hotspot, new geochronology and mapping demonstrates that the area affected by this mid-Miocene volcanism is significantly larger than previously appreciated. Three silicic calderas have been newly identified in northwest Nevada, west of the McDermitt volcanic field as well as the Virgin Valley Caldera. These calderas, along …
