Excelsior Geyser Crater
Excelsior Geyser Crater (formerly known as Excelsior Geyser) was given the name by the Hayden Geological Survey of 1871. The geyser is of the dormant fountain variety located in the Midway Geyser Basin of Yellowstone National Park. The geyser pool discharges 4,000 to 4,500 gallons (15,100–17,000 L) of 199 °F (93 °C) water per minute directly into the Firehole River. On your way up the hill to the geyser you can see this colorful runoff into the Firehole River. At one time this was a very active geyser whose eruptions were near 100 feet high in both height and width. These eruptions may have damaged the geyser's internal plumbing system. The geyser now boils as a productive hot spring most of the time. This geyser located in Midway Geyser Basin is huge and cooks with deep blue steaming water.
