New fractures and eruptions are emerging in the Upper Geyser Basin of Yellowstone Park, including a rare eruption of Ear Spring.
A Yellowstone National Park official says a geyser near Old Faithful is erupting for the first time in 14 years.
Park spokesman Neal Herbert said Thursday that Ear Spring erupted recently for only the fourth time in more than 60 years. It last erupted in 2004.
Park officials said Wednesday that scientists are observing new thermal activity in the Geyser Hill area of Upper Geyser Basin. It’s across the Firehole River from Old Faithful and is a geothermal hotspot with dozens of hot springs, geysers and fumaroles.
Some boardwalks and trails are closed in the area as vents splash water on the trails. Boardwalks around Old Faithful Geyser remain open.
Ear Spring spewed water between 20 and 30 feet high on Saturday, a level that Herbert says hasn’t been recorded at the geyser since 1957.
Park officials also took the opportunity to remind everyone that there are no signs of impending volcanic activity.
The pool’s temperature is normally around a simmering 200 degrees:
In March 2003, fourteen new steam vents opened along a 230-foot line north of Norris Basin, releasing plumes of dense water vapor and powdered glass shards in a tremendous roar.
Then, in July 2004, geysers began erupting at odd times. The park had to close off much of Norris when ground temperatures shot up in places from 80 degrees Fahrenheit to 200, and the earth near a boardwalk became more acidic and began to dissolve.
