  • A few hotspots are thought to exist below the
    North American Plate. Perhaps the best known is
    the hotspot presumed to exist under the
    continental crust in the region of Yellowstone
    National Park in northwestern Wyoming. The
    thermal energy of the presumed Yellowstone
    hotspot fuels more than 10,000 hot pools and
    springs, geysers (like Old Faithful), and
    bubbling mudpots (pools of boiling mud).
