In Wyoming, US, you might want to visit Yellowstone National Park, which was the world"s first national park. Established in 1872 after the Protection Act was signed by the then-president of the US, Ulysses S. Grant, the park is known for its flora and fauna—including Rocky Mountain wolves and grizzly and black bears—super volcano and many geothermal features, including the one we see in today"s image. The Grand Prismatic Spring is in the Midway Geyser Basin. Its display of colours is caused by microbial mats, multi-layered sheets of microorganisms, ranging from deep blues and greens to fiery oranges and reds. There is so much waiting to be explored out there, so gather your friends and get out into the wild.
