Artesia Geyser is a special kind of hot spring called a geyser. It is located in the Lower Geyser Basin of Yellowstone National Park in the United States. Artesia Geyser sits right on the edge of Firehole Lake. It is part of a group of geysers known as the Black Warrior Group. This group also includes Young Hopeful Geyser, Gray Bulger Geyser, and Steady Geyser.

What is Artesia Geyser?

Artesia is known as a perpetual geyser. This means it almost never stops erupting water. It has at least one of its two openings, or vents, always sending out water. Usually, the water shoots up no more than 5 ft (1.5 m) high.

One of Artesia's vents points towards the boardwalk where people walk by. The other vent aims towards Firehole Lake.

How Artesia Geyser Changes

Geysers can change how they erupt over time. In 1999, one of Artesia's vents shot water up to 12 ft (3.7 m) high. At the same time, the other vent only let out steam.

In 2012, Artesia started having more powerful eruptions. These eruptions happened about once every minute. The water shot straight up, and there was not much activity in between.

From 2014 to 2017, Artesia was a low "spouter." This means it was just gently spraying water all the time. But in the summer of 2018, it started having big eruptions again. These eruptions happened about once a minute. The columns of water reached four to five meters high.
