After a slumber that stretched for more than six years, the Giantess Geyser at Yellowstone National Park erupted once again on August 25, 2020.
Yes, one of the large geysers of Yellowstone National Park roared back to life after more than six and a half years of dormancy. Amazing, no?
On Tuesday, August 25, Giantess Geyser roared back to life after a period of more than 6-1/2 years without erupting.— yellowstonenps (@YellowstoneNPS) August 29, 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.
It used to erupt more frequently in the past. The 6-year gap between eruptions in the longest since at least the 80s, but it has had years-long dormant periods before. Why geysers turn off and on is something that is not well understood. They are very fragile systems.— USGS Volcanoes🌋 (@USGSVolcanoes) August 29, 2020
