Old Faithful Geyser
Old Faithful Geyser is the name given to one of the world’s biggest and most regular geysers and is located in Yellowstone National Park in Wyoming, USA.
There are over 300 geysers in Yellowstone National Park but Old Faithful Geyser is the most renowned. Old Faithful was named by the Washburn-Langford-Diane Expedition in 1870 when they first encountered the plume of white water as it shot into the sky about one hundred and twenty-five feet high.
What the Expedition found was an oval-shaped irregular aperture measuring about three feet by seven projecting a stream of hot steamed water into the sky. The Old Faithful geyser eruption schedule is extremely regular, erupting approximately every 30-90 minutes or more and lasting up to 5 minutes. The large geyser was on a mound, which was about thirty feet higher than the rest of the landscape and about five feet from the mound itself was the aperture. Read more
