Grotto Geyser is connected with at least five other geysers in the surrounding area.
Eruptions are usually preceded by an eruption from Grotto Fountain Geyser, or both Grotto Fountain Geyser and South Grotto Fountain Geyser.
But if the latter erupts on its own, it will delay both eruptions from Grotto Fountain Geyser and Grotto Geyser itself.
After Grotto has a short mode eruption, which lasts about 1 to 2 hours, Rocket Geyser usually has a major eruption.
Approximately three-quarters of Grotto's eruptions are short mode.
Grotto Geyser and Rocket Geyser erupt together.
When Grotto Geyser has a long mode eruption, which lasts from 6 to 12 hours, Spa Geyser, instead of Rocket Geyser, erupts.
