In the past, an eruption of West Triplet was a bad omen for Grand , often delaying Grand by two or more Turban cycles. Fortunately, his relationship has not been seen for years. Another relationship which doesn't seem to have changed in recent years is that West Triplet often precedes an eruption of Rift Geyser . West Triplet is a fountain-type geyser, erupting through a funnel shaped pool. The maximum height is about 10 feet.
Durations range from minutes to hours.
Intervals range from hours to days. The water level may drop some at about the time Turban erupts but will rebound. Eventually, the water over the vent begins to pulsate and low thumping noises may be heard. Sometimes the eruptions starts before overflow is reached other times it overflows before it erupts. At times, it can overflow for a long period and then drop without erupting.
