Clepsydra Geyser Description provided by Graham Meech.]

If you arrive at the Fountain group and there is no geyser erupting, you are seeing an unusual sight. Clepsydra has been erupting almost continuously since the 1959 earthquake so you should not have to rush to get a picture before it stops. Prior to the earthquake Clepsydra erupted with great regularity every 3 minutes. Since the earthquake the only thing that can cause it to stop sometimes is an eruption of Fountain geyser. During a pause in its activity you can see the beautiful yellow, orange and pink colors around Clepsydra's vents. The absence of any geyser activity and the associated quiet does not last long before Clepsydra resumes its activity having been quiet for only a few minutes.

What to look for:

With Clepsydra the unusual thing to see is when it has a pause in its eruption. If you are present during an eruption of Fountain you should listen to see if the sound from Clepsydra changes. [b]One of its vents can enter a steam phase and it starts to roar loudly[/b]. This is usually required for Clepsydra to have a chance of pausing although it will not pause every time it roars. If it is going to pause, it will usually pause within 20 minutes of the end of a Fountain eruption.
