The following is part of a series of posts about the trip Wayne and I took to Yellowstone National Park in 2009.
The Fountain Paint Pots area of Yellowstone is a little different than what one expects from this National Park. Silex Spring overflows most of the year and the overflow causes a hot environment where thermophiles thrive and cyanobacteria forms mats of orange and brown.
Some microorganisms use hydrogen sulfide which rises from deep within the earth to convert the gas into sulfuric acid which breaks down rock into bubbly clay. In the early summer they may be thin and watery from abundant rain and snow but by late summer and fall the mud is quite thick.
When we were at the mudpots it was windy and sunny so I brought my umbrella along for the walk. The smiles on other tourists' faces when they saw my polka dots added to the fun.
