Castle Geyser eruption
Old faithful geysir
Yellowstone National Park was established by US Congress as a national park in 1872,and is located primarily in the state of Wyoming,but also extends into the states of Idaho and Montana.
The geothermal features at the park are a result of water passing trough extremely hot rock underground,which is still cooling down from a volcanic eruption thousands of year ago.
In the 1960 and 1970 it was disvovered that the main feature of the park is a series of three volcanic craters.
The eruption of these three volcanoes occured 2,1 million years ago,1,3 million years ago and 640000 years ago.
The main feature of the park is the geysir old faithful,which erupts approximately every 91 minutes.
As well as the Old faithful Yellowstone has a spectacular landscape and a rich wildlife,including Grizzly bear,elk,moose,mule dear,black bear,wolverine,wolf and sometimes the seriously treathened lynx could be present.
A place to go for an adventure and to see nature perform.
