Introduction to The Geysers of
Yellowstone   Yellowstone National Park is home to some 10,000 thermal features, over 500 hundred of which are geysers. In fact, Yellowstone contains the majority of the worlds geysers. Within Yellowstone's thermal features can be seen the product of millions of years of geology at work. Much of Yellowstone sits inside an ancient volcanic caldera (the exploded crater of a volcano). The last major caldera forming eruption occurred 600,000 years ago. For hundreds of thousands of years following  that, subsequent lava flows slowly filled in most of the caldera. Even
now, in some places, nearly molten rock resides as little as 2-5 miles below the
surface. Heat from the volcanic activity makes its presence known by heating
ground water and creating the therma features we now see. The four basic types
of thermal features present in the Park are geysers, hot springs, fumaroles, and
mudpots. Many of these are concentrated in Yellowstone's major geyser basins:
Upper, Midway, Lower, Norris, West Thumb, Shoshone and Heart Lake.
