Eruptions
Grand's fountain reaches a height of as much as 200 feet (61 m), with a duration of 9 to 12 minutes. Its eruptions occur in a series of 1 to 4 (rarely as many as 5) bursts.
Sequence
Grand erupts every 7 to 15 hours. It belongs to the Grand Group (or Grand Geyser Complex), and its eruption is connected to those of the other geysers in the group, especially the adjacent Vent Geyser and Turban Geyser.
For a few hours before an eruption by Grand, Turban Geyser erupts for a duration of five minutes about every 17 to 22 minutes. Grand's eruption begins within 1 to 2 minutes of the start of one of Turban's eruptions, with Vent Geyser erupting shortly after Grand starts erupting. On occasion, Grand will stop erupting after 7 to 9 minutes, only to restart with a usually taller fountain a minute or two later. Grand has been known to rarely experience over half a dozen restarts in a single eruption period. After Grand ceases its eruption, Vent and Turban can continue to erupt for another hour.
Upon the finish of an eruption, Grand's pool is empty and takes about five hours to refill.
