Narcissus Geyser

Narcissus Geyser is a geyser in the Pink Cone Group, on Firehole Lake Drive in the Lower Geyser Basin. It erupts from a pink crater, colored by the manganese oxide that characterizes the geyserite in this group. It is set back from the other geysers in this group, behind some lodgepole pines, making it difficult to see from the road.

Eruption Pattern
This geyser alternates between major and minor eruptions. Minor eruptions take place on intervals of 2.5 - 3 hours, and start with the crater only about half full of water. These eruptions last 5 - 8 minutes, and some bursts can reach up to 30 ft.

Major eruptions occur less frequently, on intervals of 4 - 6 hours. These larger eruptions can last 13 - 20 minutes and reach heights of 50 feet.

History
Records of eruptions before the 1950s are rare, and it is unclear whether it was an infrequent performer or if eruptions simply went unnoticed.

Historically, eruptions followed the alternating long-short-long-short pattern. However, in recent years, this pattern has become less clear.
