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. If you are present during an eruption of Fountain you should listen to see if the sound from Clepsydra changes. One of its vents can enter a steam phase and it starts to roar loudly. 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.
Fountain is a spectacular geyser that, most of the time, dominates the activity of the group.
Only when Morning is active does Fountain get overshadowed. Close to the boardwalk is a large steep sided crater surrounded by a large sinter terrace. Most of the time the crater is partially filled with water which is very calm, slowly rising and falling. As its name implies, Fountain is a classic fountain-type geyser with bursts of water erupting through its large pool. The boardwalk is close enough to the geyser for observers to get sprayed with warm water during the eruption.
