Best Lower Basin
Great Fountain Geyser is a consistently erupting geyser located within Yellowstone National Park’s Lower Geyser Basin. Its notable predictability makes it the only reliably forecast geyser in the park. The geyser's eruptions create impressive terraced pools and are of interest to scientists studying...
Morning Geyser is a naturally occurring fountain geyser located within Yellowstone National Park’s Lower Geyser Basin. It was first documented in 1899 and exhibits periodic eruptions reaching heights of approximately 200 feet. This geyser is notable for its consistent eruption patterns, particularly...
White Dome Geyser is a natural geyser located within Yellowstone National Park’s Lower Geyser Basin. The notable feature is its large, white silica cone, approximately three meters high, which dramatically surrounds the active vent. This geyser consistently produces impressive eruptions and is of in...
Fountain Geyser is a natural geyser within Yellowstone’s Lower Basin, specifically the Fountain Group. It produces dramatic, intermittent eruptions reaching heights of approximately eighty feet. The geyser's behavior—driven by underground thermal activity—is notable for its predictable, though varia...
Pink Cone Geyser is a notable hydrothermal feature situated in the Lower Geyser Basin of Yellowstone National Park. It was named by the Hayden Geological Survey due to its distinctively dark, pinkish-red siliceous sinter cone, formed by years of mineral deposits. As a predictable cone geyser, it eru...
Clepsydra Geyser is a fountain-type geyser situated in the Lower Geyser Basin of Yellowstone National Park, adjacent to the Fountain Paint Pot. It was named for the Greek word klepsydra, meaning water clock, because it historically erupted with regular, clock-like intervals. Following the 1959 Hebge...
Jet Geyser is an active thermal feature in Yellowstone National Park's Lower Geyser Basin that produces narrow, high-velocity spurts of water.
Mound Geyser is a frequently active geyser in the River Group of Yellowstone's Lower Geyser Basin, near the Firehole River in Wyoming.
Tantalus Geyser is a hydrothermal feature in Yellowstone National Park, Wyoming, USA, named after the mythological Greek figure condemned to eternal near-satisfaction.
Spasm Geyser is a small, erratically erupting geyser in Yellowstone National Park's Lower Geyser Basin, Wyoming, USA, named for its spasm-like, intermittent water bursts.
Red Spouter is a hot spring and spouter in the Lower Geyser Basin of Yellowstone National Park, Wyoming, named for the reddish iron oxide coloring its discharge area.
Pink Geyser is a Yellowstone geyser in the Lower Geyser Basin's Pink Cone Group, associated with reddish sinter colored by iron and manganese oxides.
A geyser in Yellowstone National Park's Lower Geyser Basin named for the bead-like bubbling of water at its vent, located near the Fountain Paint Pot thermal area.
Spray Geyser is a minor geyser in Yellowstone National Park, Wyoming, USA, characterized by a low, wide spray pattern of hot water rather than a concentrated vertical column.
Grey Bulger Geyser is a thermal feature in Yellowstone National Park, Wyoming, USA, named for its grey-colored mineral deposits and the bulging shape of its silica-encrusted vent.
Super Frying Pan Geyser is a named hydrothermal feature in Yellowstone National Park, Wyoming, within the park's world-leading concentration of geysers.
West Sprinkler Geyser is a thermal feature in Yellowstone National Park, Wyoming, USA, named for its characteristic low-angle, spray-like discharge pattern during eruptions.
Steady Geyser is a geyser in Yellowstone National Park, Wyoming, USA, named for its relatively consistent and predictable eruption intervals compared to more erratic neighbors.
Rosette Geyser is a Yellowstone geyser in the Lower Geyser Basin, the park's largest geyser basin by area at about 11 square miles.
Flat Cone Geyser is a cone-shaped thermal feature in Yellowstone's Sentinel Meadows, one of three sinter cones described by the 1872 Hayden Survey.
Young Hopeful Geyser is a thermal feature in Yellowstone's Lower Geyser Basin, Wyoming, USA, named for the potential of its eruptions despite modest and historically irregular activity.
Narcissus Geyser is a Yellowstone geyser in the Lower Geyser Basin, notable as a member of the Pink Cone Group with Pink Cone and Pink Geyser.
Spindle Geyser is a geyser in Yellowstone National Park's Upper Geyser Basin, Wyoming, USA, named for the elongated, spindle-shaped water column it projects during eruptions.
Kaleidoscope Geyser is a small thermal feature in Yellowstone National Park's Lower Geyser Basin, recognized for its vividly colored runoff channels.
A small geyser in Yellowstone National Park's Upper Geyser Basin, Wyoming, catalogued by an alphanumeric designation among the park's hundreds of named thermal features.
Snort Geyser is a Yellowstone geyser in the Lower Geyser Basin, listed among the named thermal features of the park's broad Firehole River basin.
Ragged Spring Geyser is a hydrothermal feature named for its irregular or jagged vent structure, located within an active geothermal landscape of named springs and geysers.
A geyser in Yellowstone National Park's Upper Geyser Basin whose name evokes artesian well characteristics, situated among the dense hydrothermal features of that basin.
Morning's Thief Geyser is a thermal feature in Yellowstone National Park's Upper Geyser Basin, USA, notable for its subterranean connection that occasionally drains water from Morning Geyser.
Labial Geyser is a fountain-type feature in Yellowstone National Park's Lower Geyser Basin, characterized by its distinct, lip-like mineral edges.
