Excelsior Geyser (HD)

-------------------
Excelsior Geyser
Geysers are hot springs that episodically erupt columns of water. They occur in few places on Earth. The highest concentration of geysers anywhere is at the Yellowstone Hotspot Volcano (northwestern Wyoming, USA).
Excelsior Geyser is the namesake of the Excelsior Group of Yellowstone’s Midway Geyser Basin. Its basin has an irregular shape, with the longest dimension of the water-filled portion about 110 meters and the greatest width almost 80 meters. A jagged cliff borders most of Excelsior’s basin. Two major runoff channels drain to the north and northeast, into the Firehole River. Over 4,000 gallons of hot water are discharged every minute (see Bryan, 2018 - The Geysers of Yellowstone, Fifth Edition). Excelsior experienced very large eruptions in the 1870s, 1880s, and 1890s, followed by more or less permanent dormancy to the present day. Eruptive activity also occurred in 1985 and 2000.
Filmed from the Midway Geyser Basin boardwalk & along the Firehole River & atop Midway Bluff (pre-closure).

The dormant giant with a pretty blue hue to it

Old comment but... I don't think it's necessarily dormant, I mean it outputs around 5,800,000 gallons of water per day into the nearby river, the thing was so powerful it majorly ruptured its own plumbing system, it used to produce eruptions 300 feet high, but after all those catastrophic eruptions, when it last erupted in 1985, it only produced 80 foot high eruptions. We could see it produce massive plumes again, buuuuut that would likely require putting a cap on it.
