description Artemisia Geyser Overview
Artemisia Geyser is a cone-type geyser in the Upper Geyser Basin of Yellowstone National Park, located on Geyser Hill near the Firehole River. It is named for the sagebrush (genus Artemisia) that grows in the surrounding area. The geyser is known for its large, deep blue pool and infrequent eruptions that can reach approximately 30 feet in height, with eruption intervals varying from days to weeks or longer. Between eruptions, the pool remains quiet and is one of the more visually striking features in the Geyser Hill group.

Where is Artemisia Geyser?
Artemisia Geyser is in Yellowstone National Park's Upper Geyser Basin on Geyser Hill near the Firehole River. It is separate from Old Faithful, although both are in the Upper Geyser Basin. [National Park Service](https://www.nps.gov/places/000/artemisia-geyser.htm)
Why is it called Artemisia Geyser?
The name refers to sagebrush, the Artemisia plant, and the grey-green color of the geyserite deposits around the feature. The National Park Service specifically connects those deposits with the name. [National Park Service](https://www.nps.gov/places/000/artemisia-geyser.htm)
What does Artemisia Geyser look like when it erupts?
Its main feature is a large deep-blue pool, and its activity is more like a roiling boil than a tall jet. The National Park Service lists the eruption interval as irregular, roughly 9 to 31 hours. [National Park Service](https://www.nps.gov/yell/planyourvisit/geyser-activity.htm)
How long does an Artemisia Geyser eruption last?
The National Park Service lists an average eruption duration of about 5 to 25 minutes. Because the interval is irregular, visitors cannot treat Artemisia's 9 to 31-hour activity window as a precise schedule. [National Park Service](https://www.nps.gov/yell/planyourvisit/geyser-activity.htm)
