Yellowstone Nationalpark

Yellowstone Nationalpark

Yellowstone is the first and oldest national park in the world
and covers 3,470 square miles (8,980 km²), mostly in the
northwest corner of Wyoming. The park is famous for its
various geysers, hot springs, and other geothermal features
and is home to grizzly bears and wolves, and free-ranging
herds of bison and elk.
Yellowstone Caldera is the largest volcanic system in
North America. It has been termed a "supervolcano"
because the caldera was formed by exceptionally large
explosive eruptions.

We stayed 2 days in the park, which was the most
impressing trip of our whole life.
