The tallest active geyser is Steamboat in Yellowstone

Its eruptions can throw water more than 100 metres up

Steamboat Geyser in Yellowstone National Park has produced eruptions reaching roughly 90 to 120 metres, taller than any other active geyser. Unlike Old Faithful it is unpredictable, sometimes erupting for days on end and sometimes staying quiet for years. The park sits over a volcanic hot spot that heats groundwater far below the surface.
