Pink Geyser is a fountain-type geyser in the Lower Geyser Basin of Yellowstone National Park in the United States.
Pink Geyser is part of the Pink Cone Group. Other geysers in this groups include Bead Geyser, Box Spring, Dilemma Geyser, Labial Geyser, Narcissus Geyser, and Pink Cone Geyser.[2]
Eruptions of Pink Geyser last about 12 minutes and reach 20 feet (6.1 m) in height and ends with a steam-phase. The interval between eruptions is 2 to 12 hours averaging about 6.5 hours.[3]
Pink Geyser was named for the shell-pink color of the geyserite around its vent which is a caused by the presence of manganese and iron oxides. The same color marks other geysers in the immediate area, including Pink Cone Geyser and Narcissus Geyser, indicating some communality but they do not appear to interact.
Pink Geyser is susceptible to seismic activity. Before the 1983 Borah Peak earthquake, it only erupted twice a day. Following the quake, its interval shortened to between 5 and 7 hours. The 2002 Denali earthquake shortened the intervals even more.[4]
