Clepsydra Geyser
The name of this geyser comes from the Greek word for “water clock”, which is most appropriate both for its nearly continuous performance today and its remarkably regular 3-minute interval before the great Yellowstone quake of 1959. On a cool morning, as most are even in the summer, the steam wafts far from the spouting 197-degree water plume and marks this geothermal delight’s location from miles away.
