Yellowstone National Park, Wyoming Magnet

Yellowstone National Park is a nearly 3,500-square mile wilderness recreation area straddling the U.S. states of Wyoming, Montana, and Idaho. It's widely considered the first national park in the U.S. and is also widely held to be the first national park in the world. It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone is known for its wildlife and its many geothermal features, especially Old Faithful geyser, one of its most popular attractions. The park boasts hundreds of species of mammals, birds, fish, and reptiles, including several that are either endangered or threatened, providing opportunities for wildlife viewing.
