Facts You’ve Never Heard About Yellowstone

We’ve praised all the wonders of Yellowstone National Park in this very long post. And we are still not finished. 😛

Yellowstone fascinated us not only with its breathtaking natural beauty, but also with its unique geothermal features. Here we collected all the interesting facts and numbers about the park you may never heard of!
