USA: Yellowstone National Park

On Tuesday I got a postcard from the USA.

It shows the Yellowstone National Park. The Yellowstone National Park was established in 1872 by President Ulysses S. Grant and is thus the oldest national park in the World. It is famous for its wildlife and its many geothermal features including the largest supervolcano on the continent. The park is one of the few remaining intact large ecosystems in the northern temperate zone of the earth. In 1978 it became one of the first UNESCO World Heritage Sites.
