Yellowstone National Park. Besides being the world's first national park, Yellowstone is also teeming with wildlife, gorgeous landmarks and views, and a place for a fun family vacation. Right?
Beneath Yellowstone National Park is one of the most dangerous things on our planet.
Is it a kind of bacteria or virus? No. Is it a toxic species of animal? Wrong again. As you walk peacefully down the boardwalk to Old Faithful, (one of the largest and most talked about geysers in the world) sipping from your water bottle on a hot Yellowstone day, do you know what's below your feet? Deeper down than the dirt and insects and hot water from the geysers, there is also a super volcano, one of the largest in the world.
The Yellowstone Caldera.
