Old Faithful Geyser is the most predictable geyser in Yellowstone
National Park.
The Old Faithful Geyser, located in Yellowstone National Park, is
perhaps the world's most famous geyser. Old Faithful was named in
1870 by the Washburn Party and was the first geyser in the park to
receive a name. An eruption can shoot 3,700-8,400 gallons
(14,000-32,000 l) of boiling water to a height of 106-184 feet
(30-55 m) lasting from 1.5-5 minutes. The intervals range from
65-92 minutes with 91 minutes being the average. More than 137,000
eruptions have been recorded. Harry M. Woodward first described a
mathematical relationship between the duration and intervals of the
eruptions (1938). Old Faithful is not the tallest or largest geyser
in the park. With an error of 10 minutes, Old Faithful will erupt
65 minutes after an eruption lasting less than 2.5 minutes or 92
minutes after an eruption lasting more than 2.5 minutes.

Half of our team were already here 16 years ago, now the four of us enjoyed this classic as well as the many sightings of bison, deer, and other wildlife. Thanks for having a cache here.
