Narcissus is a fountain-type geyser. It has major and minor eruptions. Minor eruptions occur after shorter intervals. Because the pool has not had time to completely refill after the last eruption, these eruptions are taller. Minor eruptions last about 5 to 8 minutes and reach over 20 feet.
Major eruptions occur after the pool has had time to fill.
These eruption lasts up to 15 minutes but only reach about 15 feet. Pink is a fountain-type geyser. The name refers to the pink coloration of its sinter. This same coloration is also seen at Pink Cone Geyser and Narcissus Geyser. Prior to the 1983 Borah Peak earthquake Pink only erupted about twice a day.
