Geysers, Thermophiles, And Hot Springs
America's first and most famous National Park is Yellowstone National Park. Visitors flood the 3,472 square mile super volcano to view geysers, hot pots, mud volcanoes, hot springs, and other geothermal activity unlike anything in the world. While Old Faithful may be the tried and true geysers of choice, that shouldn't downplay its more sporadic but equally awesome siblings around the park. While the treacherous ground is a major reason to stay on the park's broad walk trails, that doesn't stop hearty bison, elk, wolves, bears and other native species from flourishing within the park.
