Clepsydra Geyser


This nearly constant performer splashes from several vents and its steam can be seen throughout the Lower Geyser Basin. Its name is Greek for water clock, and was given because the geyser used to erupt regularly every three minutes. Since the 1959 Hebgen earthquake, however, Clepsydra erupts almost without pause. Sometimes it quits during Fountain Geyser's eruptions.
