             Steamboat, World's Tallest Active Geyser, Erupts
                       In Yellowstone National Park

Visitors to Yellowstone National Park's Norris Geyser Basin were awarded
with a unique experience when Steamboat, the world's tallest active geyser,
erupted after an almost two-year hiatus.  Eruptions of Steamboat Geyser are
entirely unpredictable.

On Monday, May 23, 2005, at approximately 2:40 p.m., a National Park
Service employee reported that Steamboat Geyser was erupting.  Steamboat
Geyser rarely erupts in its major phase.  More commonly, Steamboat ejects
water in frequent bursts of 10-40 feet.  During a major eruption, Steamboat
can reach heights of over 300 feet, showering viewers with mineral-rich
waters; yesterday's eruption expelled approximately 11,500 gallons of
water.   For hours following its rare 3-40 minute major eruptions (water
phase), Steamboat thunders with powerful jets of steam; this steam phase
can continue as long as 12 hours after the water cessation.

Steamboat's intervals vary from three days to fifty years (Steamboat was
dormant from 1911-1961).  In recent years, Steamboat has erupted in 1989 (3
times), 1990 (1 time), 1991 (1 time), 2000 (1 time), 2002 (2 times) and
2003 (3 times).
