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."
