No, this time it's not Yogi Bear :)
Yellowstone National Park, the most well-known natural reserve in the US. and was the first to be established in the country in 1872. The park spans through three states, the major part is in Wyoming but it extends into Montana and Idaho as well.
Among it's vast number of natural formations, from mountains to canyons, from rivers to lakes, one is the Old Faithful geyser. It is rated as "the most predictable geothermal feature on Earth" 'cause it erupts in every 92nd minute. Wow, that's news to me! The eruptions can be 40-50 meters high and the temprature of the thermal water is so hot that people used to take their laundry into the geyser to wash... But it was a long time ago :)
