Yellowstone: Mud Volcano and Sulphur Caldron

The Mud Volcano area is on the east part of the south loop in Yellowstone National Park, north of Hayden Valley. The hillside was heavily forested until 1978 when the ground temperature reached 200° F following a series of earthquakes. Just a reminder that Yellowstone is constantly changing.

Grizzly Fumerole

The area is one of the more odoriferous in the park. 

For best results turn on your sound.

The Sulphur Caldron is nearly as acidic as battery acid.
