description Clepsydra Geyser Overview
Clepsydra Geyser is a fountain-type geyser situated in the Lower Geyser Basin of Yellowstone National Park, adjacent to the Fountain Paint Pot. It was named for the Greek word klepsydra, meaning water clock, because it historically erupted with regular, clock-like intervals. Following the 1959 Hebgen Lake earthquake, the geyser's plumbing system shifted, causing it to erupt almost continuously. It shoots water up to 45 feet in the air, making it a prominent feature of the park's thermal areas.
