New thermal activity reported in Yellowstone’s Upper Geyser Basin
Over the last several days, there has been new thermal activity in the Geyser Hill area of the Upper Geyser Basin. This includes new erupting vents splashing water on the boardwalks, surface fractures and a rare eruption of Ear Spring on Sept. 15.
Geyser Hill lies across the Firehole River from Old Faithful and features dozens of hot springs, geysers and fumaroles.
For the public’s safety, some boardwalks and trails in the Geyser Hill area have been temporarily closed. Closure signs are posted. Find additional information at the Old Faithful Visitor Education Center during business hours.
The boardwalks around Old Faithful remain open.
There are no signs of impending volcanic activity in the park.
