Bulger Geyser, Natural geyser in Upper Geyser Basin, Yellowstone National Park, US.
Located 200 feet south of Grand Geyser, Bulger Geyser displays both minor eruptions lasting seconds and major eruptions continuing for 12 minutes.
The geyser's crater formation has been continuously monitored since 2010, providing scientific data about geothermal activity in Yellowstone National Park.
Scientists and geologists study Bulger Geyser as part of their research into the patterns and behaviors of thermal features in Yellowstone.
The water temperature during eruptions reaches 198 degrees Fahrenheit, requiring visitors to maintain a safe distance from the thermal feature.
