Watch Yellowstone’s Prismatic Spring Display a Beautiful Rainbow of ColorsThe Rainforest Site
Yellowstone National Park is known for many natural wonders, but this beautiful footage shows that the Grand Prismatic Spring may have topped all of the others. This spring glows in all of those amazing colors because of bacteria that live on the edges of the mineral rich water. On top of that, it's huge: the spring is third-largest in the world at 300 feet in diameter.
The Grand Prismatic Spring is an amazing feature of Yellowstone. Help protect it and the other incredible, wild gifts that our national parks have to offer by signing this petition.
