Geyser Country

Nowhere in the world is there a more varied or larger collection of hydrothermal features than there is in Yellowstone. Spouting geysers, colorful paint pots, terraced springs, steaming fumaroles, boiling hot pools and bubbling mud pots, in a landscape of forest and browsing elk, creating a feeling of the world as it was before, essentially changed only by nature's own forces.

The most famous of all geysers is Old Faithful - this signature of Yellowstone is neither the largest nor the most predictable of the park's more than ten thousand hydrothermal features.
