Clepsydra Geyser located in protected area Yellowstone National Park
Clepsydra Geyser is a geyser in the Lower Geyser Basin of Yellowstone National Park in the United States.
Clepsydra plays nearly continuously to heights of 45 feet (14 m). It was named by T. B. Comstock during the 1878 Captain Jones expedition, with its nomenclature derived from the Greek word for water clock. Prior to the 1959 Hebgen Lake earthquake, it erupted regularly every three minutes.== References ==
