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.
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 .
Yellowstone National Park is symbolic of the American West to many. It became the world’s first national park when President Ulysses Grant signed it into existence in 1872.
Of the many calderas formed by the Yellowstone Hotspot, including the later Yellowstone Caldera, the Henry's Fork Caldera is the only one that is currently clearly visible. The Henry's Fork of the Snake River flows through the Henry's Fork Caldera and drops out at Upper and Lower Mesa Falls.
Scientists working in Yellowstone National Park say the supervolvcano underneath may blow sooner than thought and could wipe out life on the planet. Yellowstone supervolcano may be only decades ...
Scientists discover that the volcano under Yellowstone is much bigger than previously thought.
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.
