Fountain Paint Pot
Yellowstone mud pool
The Fountain Paint Pot (often pluralized) is a mud pot located in Lower Geyser Basin in Yellowstone National Park.
The Fountain Paint Pot is named for the reds, yellows and browns of the mud in this area. The differing colors are derived from oxidation states of the iron in the mud. As with all hot springs, the heat in the caldera forces pressurized water up through the ground, which is expelled here. Also, rising gasses cause the bubbling action. The bubble action in the mud varies with the seasons. In the early summer, the mud is watery from the high water table due to rain and snow melt. By the end of summer, the mud is much thicker as the water table drops.
Several significant geysers erupt near the Paint Pots, notably Fountain Geyser, which usually has several large eruptions a day; Clepsydra Geyser, which is active most of the time except following an eruption of Fountain; and powerful but erratic Morning Geyser, active in the latter part of 2018 following a dormancy of nearly five years. These features and others are reachable by a short boardwalk trail from the parking lot on the main road through Lower Geyser Basin.

Why this record matters
“Fountain Paint Pot” is worth following because a concise public description often conceals a longer documentary argument. Here, Fountain, Paint and Yellowstone provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 18, 2026. The linked authority identifier is Q8565025. Authority coordinates are 44.551, -110.806. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
