There are few places in the United States that provide such a deep and fascinating insight into geology as does the Yellowstone National Park that is not only known for its volcanic activity but also for its many magnificent waterfalls and wild rivers.

The Sinter Terraces of Mammoth Hot Springs are full of lime and other minerals that have created several constantly growing terraces from the resultant sediment and in the shallow basins between the steps of the terraces there are also various algae and bacteria that are responsible for the brilliant colours of the rocks.

The development and formation of the park’s landscape is subject to constant change as the hot springs within the earth provide a constant source of energy.

The Yellowstone National park is far more than just a land of geysers: its almost nine thousand square kilometres are one of the most remarkable regions on the North American Continent.
