Inscription. In the 1880s Excelsior Geyser erupted in bursts 50 to 300 feet high. The thermal violence formed the jagged crater and apparently ruptured the geyser’s underground system, causing eruptions to cease after 1890.

On September 14, 1985, Excelsior roared back to life with forty-seven hours of major eruptions. It is impossible to predict when this dormant but powerful geyser’s next eruption will occur.

More about this marker. The background photo carries the caption, "Frank J. Haynes photographed this eruption in 1888. Like most geysers, Excelsior is unpredictable, with no discernible patter to its eruptions."

On the lower right is a photo with the caption, "Though its eruptions have been erratic, the geyser’s outflow is nearly constant, pumping more than 4000 gallons of boiling water per minute over the crater rim into the Firehole River."
