A series of potential eruptions have been reported from the world's largest active geyser at Yellowstone National Park. If confirmed, they would be the first since 2014.

Park officials said employees reported seeing an eruption at the Steamboat Geyser in northwest Wyoming Thursday evening.

Geologists comparing the eyewitness reports to remote thermal sensors believe the activity could be a series of minor eruptions.

Steamboat is located in a part of the park that’s snowed in much of the year. Roads into the area currently are closed for spring plowing.

Geysers are constricted hot springs that erupt as the water heats up. Steamboat’s major eruptions can shoot steam to heights of 300 to 400 feet.
