Yellowstone National Park, Wyoming

It's a wonderland. Old Faithful and the majority of the world's geysers are preserved here. They are the main reason the park was established in 1872 as America's first national park an idea that spread worldwide. A mountain wildland, home to grizzly bears, wolves, and herds of bison and elk, the park is the core of one of the last, nearly intact, natural ecosystems in the Earth s temperate zone.

Mud Volcano

In 1870, explorers stood in awe as Mud Volcano spewed mud into the treetops, shaking the ground with each eruption. Two years later it was a pool of bubbling, muddy water. Mud Volcano had blown itself apart.
Hydrogen sulfide gas rising from Yellowstone's magma chamber causes the rotten-egg smell.
Microorganisms, or thermophiles, use this gas as a source of energy, and then help turn the gas into sulfuric acid. Sulfuric acid breaks down the rock and soil into mud.
Many of the colors are vast communities of thermophiles, but some of the yellow is pure sulphur.
When iron mixes with sulphur to form iron sulfide, gray and black swirls sometimes appear in the mud.

Liberty Cap was named in 1871 by the Hayden Survey party because of its marked resemblance to the peaked caps worn during the French Revolution. Its unusual formation was created by a hot spring whose plumbing remained open and in one location for a long time.
