Geysers - John Seach

A geyser is a vent from which hot water and steam are violently emitted.
They are very rare but well known and extensively studied.
Requirements for geyser formation include fractured rocks and boiling water at a shallow depth.

Regular eruptions (Old Faithful, Yellowstone, USA)
