Yellowstone National Park is famous for its unparalleled beauty but there’s much, much more happening in this breathtaking spot.

Microbes found in Yellowstone National Park's thermal pools have structures so ancient that scientists now believe that they could be close to the root in the universal tree of life. These microbes are becoming the models for understanding the biology necessary for life at high temperatures.

Alien Life

There are places in Greater Yellowstone where the snow never melts, or at least, it never used to. Climate change is causing Yellowstone’s ice patches to recede, so many archaeological treasures—if not rescued—will disintegrate within days.

Frozen Archeology

Greater Yellowstone sits on top of a volcanic hot spot where devastating geological events unfolded. The result? A bizarre cemetery of fossilized forests that contain the remains of trees that died from molten lava, ash, and mud around 50 million years ago.
