After a slumber that stretched for more than six years, the Giantess Geyser at Yellowstone National Park erupted once again on August 25, 2020.
The Giantess Geyser, which is located in Wyoming, historically erupted two to six times per year, according to the National Park Service (NPS).
According to the park service website, “infrequent but violent” eruptions characterize Giantess Geyser:
“Infrequent but violent eruptions characterize Giantess Geyser. This fountain-type geyser erupts in several bursts 100 – 200 ft (30 – 60m) high. Eruptions generally occur 2 – 6 times a year.
“The surrounding area may shake from underground steam explosions just before the initial water and/or steam eruptions.
The United States Geological Survey (USGS) said Saturday that Giantess Geyser used to erupt more frequently in the past.
The six-year gap between eruptions was the longest since at least the 1980s, but the geyser has had years-long dormant periods before.
