Splendid Geyser is part of the Daisy Group.

Eruptions are more likely if a storm front reduces barometric pressure and lowers the boiling point of water around the geyser.

In times when Daisy goes dormant, Splendid becomes very active.

In rare occasions, both geysers will be active at the same time, leading to a "dual eruption".

During a concert (dual) eruption Daisy and Splendid are both much stronger than usual.
