Geyser, Upper Geyser Basin

Upper Geyser Basin is the best place in Yellowstone to see geysers erupt. It is home to Old Faithful, the best-known Yellowstone geyser, as well as five out of six predicted geysers in the park. What's more, Upper Geyser Basin boasts the highest concentration of geysers in the world. There are more than 150 of these hydrothermal features in just one square mile! But before you journey to this richly rewarding corner of America's first national park there are two things all families should note. 1. Upper Geyser Basin is teeming with tourists in summer time. 2. A plan is required to catch one or more geysers in action.

Here are a few tips to make the most of a trip with kids. Make Old Faithful Visitor Center your first stop on arrival. Check the board for eruption times and ranger-led programs. Hike boardwalks and paved trails in the early morning or late afternoon; the weather is cooler and crowds are thinner. Time your walks to coincide with geyser eruptions. Choose Morning Glory Pool Trail over Geyser Hill Loop. Grand, Castle, Daisy and Riverside - all predicted geysers - are on the trail to Morning Glory Pool. Attend at least one ranger-led program; they are both educational and fun. Relax at historic Old Faithful Inn. Both the terrace and lobby are great spots to sit.

There are lots of fun facts about geysers. Did you known that:

  • Geysers are a type of hydrothermal feature just like hot springs, mud pots and fumaroles.
  • Like all other hydrothermal features geysers are heated by molten rock called magma far beneath the earth's surface.
  • Geysers need three things to form: heat, water and rock. To erupt, geysers need the right mix of this volatile three.
  • Geysers differ hot springs in one significant way; the cracks in a geyser's rock are too narrow for steam and water to flow.
  • Geysers erupt hot water and steam but only do so when the pressure is great enough to force hot, underground water through the narrow pipes of its plumbing system.
  • Some geysers erupt regularly others rarely erupt. Only six Yellowstone geysers - Old Faithful, Castle, Grand, Great Fountain, Daisy and Riverside - are predicted by park rangers.
  • Once a hydrothermal feature erupts it is called a geyser yet geysers that no longer erupt are never called anything but.
