Detailed Description

Site of April 15, 2024, hydrothermal explosion on Porcelain Terrace, Norris Geyser Basin, Yellowstone National Park.  The small crater and disrupted ground are in silica sinter deposits that formed in the past two years, since water has been flowing from the terrace into Nuphar Lake (off photo to right), and angular fragments of ejecta on top of the sinter are evidence that the crater formed due to a small explosion.  USGS photo by Mike Poland, May 18, 2024.
