Geocache Description:

The coordinates will take you to a NPS informational panel along the Fountain Paint Pots trail in Yellowstone NP. There is a $25 entrance fee valid for 7 days which can be used for both Yellowstone and Grand Tetons NPs. It is 1/5 of a mile walk from the parking lot to the paintpots. This earthcache is meant to teach how mudpots are formed and what makes them different from other hydrothermal features (geysers, hot springs, etc.).

Fountain Paint Pots are part of Lower Geyser Basin in the Firehole River Drainage. They are what is referred to as mudpots, which form when there is not enough water to support a geyser or hot spring. Did you notice that on your way to the paintpots, you went slightly uphill? That’s because they are on a raised platform, meaning they can’t as easily access the underground water table as the geysers to the west.

The formation of mudpots is caused by the following:
1. The underground magma chamber of the Yellowstone volcano heats up the underground water, causing it to boil.
2. The boiling water rises through the cracks in the rhyolite and emerges at the surface.
3. Heat loving thermophiles in the water then convert some of the gases in the water to sulfuric acid.
4. The shortage of water allows the sulfuric acid to accumulate which, over time, breaks down the rhyolite into a clay called kaolinite.
5. Minerals in the water (such as iron) change the color of the clay because of the bubbling action of the paintpots.
