Clepsydra Geyser

Many geysers are quite active in Yellowstone National Park. Clepsydra Geyser is a very busy geyser in the Lower Geyser Basin. It never rests - it gushes, spurts, spews and shoots small plumes of steam into the air. Before the 1959 earthquake, Clepsydra Geyser erupted frequently; now it just plays continuously.
