The Excelsior Geyser pool discharges 4,000 to 4,500 gallons (15,100-17,000 l)[1] of 199°F (93°C)[2] water per minute. Until 1890, it was an active geyser that often erupted to 300 feet (91 m) high. It is believed that powerful eruptions damaged its internal plumbing system, and it now boils as a hot spring most of the time.
