Yellowstone’s Upper Geyser Basin is showing increased signs of thermal activity, after hot plumes of water erupted from the ground several feet up in the air, forcing authorities to shut down parts of the park over the fear of new geysers forming. New vents were seen blasting water and steam across the basin area in Geyser Hill, ever since the Ear Spring erupted on Saturday. Authorities have attributed the

rise in geothermal activity to Saturday’s eruption, after several new surface fractures and splashes of water were spotted at the Upper Geyser Basin in . On Tuesday, spouts of water shot from the ground west of Pump Geyser and north of Sponge Geyser, also ejecting large amounts of hot steam. The new feature, which is an eight-foot diameter, continues to show increased signs of activity after geologists observed the ground rising and falling by six inches every 10 minutes. READ MORE
