Grand Geyser
The Grand Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park in the United States. It is the tallest predictable geyser known. Grand erupts every 8-12 hours, and its fountain reaches a height of 150-180 feet, with a duration of 8-10 minutes. It will often undergo a second, higher eruption immediately after the first.
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
