YELLOWSTONE NATIONAL PARK – The Yellowstone Volcano Observatory reports a rare eruption of Ear Spring on Geyser Hill, just across the Firehole River and within sight of Old Faithful.
Water shot 20-to-30 feet out of the spring and spat out rocks, old coins, cans and other debris thrown into the spring over the years.
A small area around the spring is rising and falling about six inches every 10 minutes and nearby a new, small geyser, or spouter, has erupted directly under the boardwalk.
Scientists say there are no signs of new volcanic activity in Yellowstone, but they say a small hydrothermal explosion could happen at any time.
Such an event would throw hot water and rocks for several hundred feet so park officials have closed some boardwalks near the new activity as a safety precaution to protect the public.
