       When Wyoming was still a territory, Lieutenant Gustavus Doane, head of an exploring expedition, noticed something strange when looking out from the top of a mountain. He noticed that there was a giant volcano. But the Lieutenant, even though he made a good guess, thought wrong: in his mind, the ancient crater was extinct.

    ldfthflgysr.jpgTwenty craters have been in existence since mighty sheets of ice covered Yellowstone National Park. The volcano is known to be the cause of all the geysers, mud pots, terraces, and hot springs in the park.

When we went to Yellowstone, we liked seeing the mud pots (even though they smelled like rotten eggs) and we saw Old Faithful erupt three times. Then we went to Morning Glory Pool (a multicolored hot springs.) But, while we were there, we didn't see any symptoms that the supervolcano's blast was going to happen soon.

    Earthquakes have been happening recently (which is a sign that the park could explode soon). However, scientists say the eruption could happen anytime from next week to the next millennium. The future is anybody's guess!
