A geyser that erupted last week in Yellowstone National Park fired water and rock debris up to 600 feet (180 meters) into the air, scientists say — six times higher than was initially reported.
Geologists at the Yellowstone Volcano Observatory (YVO) estimated the height of the plume by examining photos posted on social media. They also pinpointed the site and depth of the eruption, which occurred July 23 at Black Diamond Pool in Biscuit Basin, about 2 miles (3.2 kilometers) northwest of the famous Old Faithful geyser.
