Twin Geyser

Twin Geyser is a misnomer - this is actually one geyser with two vents from which the water spews. The underground steam and pressure release the water in a dramatic spray. With its two vents it's capable of ejecting water jets up to 35 m (120 feet) high and is thereby the largest geyser of West Thumb Basin. Unfortunately, the eruptions are unpredictable and infrequent.
