Since 1870, 22 people have died in the park after falling into the pools and geysers. One of the most recent deaths, in 2016, involved a man trying to soak in a geyser in the park. The man fell into the water and was boiled to death.
Old Faithful “plays” prior to an eruption with splashes of boiling water that may reach as high as 20 feet (6 m). A full eruption usually begins from this play. Once the eruption starts, the splashes grow larger and larger until the eruption reaches its full height.
Drownings have resulted in five known deaths in the park. Looking at all national parks, the survey indicated that falls were by far the most common way to die, accounting for a total of 245 deaths.
Geysers like Old Faithful in Yellowstone National Park erupt periodically because of loops or side-chambers in their underground plumbing, according to recent studies by volcanologists at the University of California, Berkeley.
The mornings (dawn until 11 a.m.) and evenings (6 p.m. until dusk) are perfect window times for beating the tour groups and family wagons and securing a spot with an uninterrupted view. If you prefer the morning, all you need is a trusty alarm clock, maybe a strong cup of coffee and an early start to the day.
However, Yellowstone is also an active geothermal area with hot springs emerging at ~92°C (~198°F) (the boiling point of water at Yellowstone's mean altitude) and steam vents reported as high as 135°C (275°F).
You can drive through Yellowstone National Park via the 7-hour Grand Loop in the summer months, taking in Old Faithful, Mammoth Hot Springs and Yellowstone Lake. In winter most roads close so you'll have to join a snow coach tour or hire a snowmobile.
