Steamboat Geyser

A huge plume of steam and water rising over three times the height of the surrounding pine trees as seen during an eruption several decades ago.

The world's tallest active geyser, Steamboat can erupt to more than 300 feet (90m), showering viewers with its mineral-rich waters.   For hours following its rare 3 to 40 minute major eruptions, Steamboat thunders with powerful jets of steam.  As befitting such an awesome event, full eruptions are entirely unpredictable.  In recent years, Steamboat has had several major eruptions. More commonly, Steamboat  has minor eruptions and ejects water in frequent bursts of 10 to 40 feet.
