Fountain Paint Pot
Fountain Paint Pot flows at 136 degrees Fahrenheit within Yellowstone's Lower Geyser Basin, emerging just 135 feet from the Grand Loop Road and famous for its colorful mud derived from oxidized iron in varying states that produce reds, yellows, and browns.
The feature sits at 7,307 feet elevation in Gallatin County at the center of one of Yellowstone's most accessible and diverse thermal areas. The Paint Pot's appearance changes seasonally with water levels, becoming thicker mud in dry periods and more fluid in wet seasons. Surrounding features include Fountain Geyser and numerous hot springs that create a concentrated thermal display. The landscape transitions from lodgepole pine forest to barren thermal ground altered by acidic steam and water. Annual precipitation of 28 inches and 141 inches of snow influence the mud's consistency throughout the year.
The name describes both the colorful appearance and paint-like consistency of the thermal mud. Early explorers including the Washburn Expedition of 1870 documented the feature, which became one of Yellowstone's iconic attractions due to its vivid colors and accessible location. The mud pot's activity varies with underground water levels and heat flow, occasionally transitioning between spring and fumarole behavior. The National Park Service maintains boardwalks around the feature, installed progressively from the 1930s onward.
Visit via the Fountain Paint Pot Trail, a half-mile boardwalk loop accessible from the Grand Loop Road between Madison and Old Faithful. The paved path is wheelchair accessible and suitable for all visitors. Morning light enhances the colorful mud's appearance for photography. Peak summer crowds can make the boardwalk congested; shoulder seasons offer pleasant conditions with fewer visitors. Winter access requires snowmobile or snowcoach permits from the west entrance.
