Shell Spring, Biscuit Basin, Yellowstone National Park, Wyoming, August 6, 2010 (Pentax K10D)
Shell Spring’s name is derived from the shape of the it’s crater, a geyserite structure vaguely reminiscent of a giant clam shell. It is a cyclic geyser with several hours of recovery between the long lasting active phases. Although the spring is only 2 feet deep, in 1930 a 3-year-old Idaho girl fell into it and, later, died from her injuries.1
Temperature 200°F Interval 1.5 to several hours. Duration 20-90 seconds. Height 5-8 feet. “Before an eruption, water in the crater begins to rise and may boil. Heavy churning then occurs, setting off the first small, weak eruption. As the eruptions subside water begins to lower and drain back into the crater.” 2
