Windows into Wonderland

Receiving the runoff from many of Yellowstone’s geysers and hot springs, the Firehole River is of great scientific interest as one of the best known examples of a naturally thermally altered river. Born in the mountains of Yellowstone, the Firehole River becomes truly special as it flows through the park’s major geyser basins. Photographs, illustrations, in-trip activities, and video footage guide you on a journey downstream. Investigate changes in water chemistry, temperature, and habitats as the river swallows the runoff from geysers and hot springs. Learn how this naturally warmed stream may serve as a model for predicting long range effects of human-caused thermal pollution on other waterways.
