Labial Geyser, Cone geyser in Lower Geyser Basin, Yellowstone National Park, US.
Labial Geyser is a cone geyser in Lower Geyser Basin within Yellowstone National Park that expels water through three separate openings. The main vent shoots water at an angle, while the other openings follow their own discharge patterns.
This geyser belongs to the Pink Cone Group within Yellowstone's larger geothermal system, which traces back to the park's founding. The hydrothermal features in this area have evolved continuously since their early documentation.
The geyser gets its name from the distinctive lip-like openings of its vents, a feature that shapes how people talk about and recognize this thermal feature. Visitors notice this unusual form immediately when they approach the site.
Eruptions typically occur every 5 to 9 hours, with each burst lasting about one minute. Watch for preparatory water movements before the main event, as nearby satellite geysers often respond during the same period.
Before erupting, the geyser displays a rhythmic pattern of water rising and falling inside its main vent, signaling what is about to happen. This preparatory display gives observers a chance to anticipate the full eruption.
