Yellowstone National Park
Yellowstone National Park ligt in het noordwesten van Amerika, midden in de Rocky Mountains. Yellowstone is in 1872 tot Nationaal Park uitgeroepen en is daarmee het oudste Nationale Park van de Verenigde Staten.
Yellowstone is bekend om z'n veelzijdigheid aan natuurverschijnselen en dierenleven. Het park heeft bijvoorbeeld meer dan tienduizend geysers en warmwaterbronnen, honderden elanden en duizenden wapitiherten en bizons.
Officially designated by UNESCO as World Heritage Site, this site is to be safeguarded for the future as a testimony to its enduring past.
Yellowstone National Park is in the north-west of the United States,
in the heart of the Rocky Mountains. Yellowstone was proclaimed a National Park in 1872, making it the oldest national park in the United States. In 1988, an enormous forest fire destroyed a large section of the park. Step by step, nature is trying to regain her old grandeur.
The park has more than ten thousand geysers and hot water springs.
The most famous geyser is without doubt the "Old Faithful", which every 70 minutes sprays its watery plume some forty metres in the air.
In the area surrounding Old Faithful most of the warm springs and geysers of the park can be found. For a geyser you need water and heat, and of course an exhaust system. In Yellowstone all three factors are there. A hot stream flows just below the earths crust.
This so-called magma heats up the rain and meltwater that seeps through, which is subsequently pressurised and forced back to the surface again. The result: hot springs, mud pools, steam and explosive geysers.
