Yellowstone National Park's mystical landscape.
Yellowstone National Park, the world's very first national park, has not lost its charm over the past one hundred years as tourists grow in number every year to personally witness its natural wonders including volcanic features such as the Grand Prismatic Spring. Here, in the late afternoon, a group of teenagers walk past the spring taking selfies.
