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.

Labial Geyser sits in the Pink Cone Group of the Lower Geyser Basin, alongside Bead Geyser, Box Spring, Dilemma Geyser, Narcissus Geyser, Pink Geyser and Pink Cone Geyser. Its two satellite geysers, known as Labial's Satellite Geyser, respond to eruptions of the main vent but have also been seen erupting independently, and their intervals are not predictable. Full eruptions of the satellites last 12 to 15 minutes, with the eastern vent dominating at 1.8 m while the western vent reaches 3.0 m.

Labial Geyser sits in the Pink Cone Group of Lower Geyser Basin, alongside Bead Geyser, Box Spring, Dilemma Geyser, Narcissus Geyser, Pink Geyser and Pink Cone Geyser. Its two satellite geysers, known as Labial's Satellite Geyser, usually react to eruptions of the main vent but have also been seen erupting independently, and their intervals cannot be predicted.

Eruptions occur at intervals of 6 to 9 hours, and each lasts less than one minute. In the final minutes before an eruption, the surging in the vent becomes violent. A second eruption sometimes follows within 30 minutes, and the two satellite geysers may also erupt independently.

Labial Geyser has two satellite geysers that respond to its eruptions but have also been seen erupting independently, and their intervals are not predictable. Full eruptions of these satellites last 12 to 15 minutes, with the eastern vent reaching 6 feet and the western vent 10 feet.
