Geothermal Features

The constant bubbling of mineral infused, hot water leaves colorful, thin layers of sediment throughout the geothermal areas of Yellowstone National Park.  The hot spring in the foreground of this photo reminds me of a lunar crater while the colorful cliff and distant steam behind it add to the other-worldliness of the scene.

Dragon’s Mouth

One of the geothermal features we liked best at the Mud Volcano in Yellowstone National Park was “Dragon’s Mouth”.  The combination of steam and the deep, hissing and gurgling sounds that occasionally come from the vent make the name somewhat self explanatory when you’re there.
