Introduction

Grand Geyser in Yellowstone's Lower Geyser Basin is one of the most predictable geysers in Yellowstone and the world, famed for its spectacular multi-vent eruptions. It erupts about every 5 to 9 hours, with each eruption lasting about 10 minutes; multiple vents fire water columns simultaneously up to 60 meters, the jets crossing like fireworks, Yellowstone's only multi-vent geyser. About 4 minutes before an eruption, the water level in the vents first overflows then drops, giving visitors a rare warning window. The boardwalk in front of the visitor center rings the geyser with shade ramadas and benches, one of the few comfortable spots to wait for an eruption in Yellowstone. Predicted eruption times are posted at the visitor center, making the wait informed.
