Yellowstone National Park, the oldest, one of the largest, and probably the best-known national park in the United States. It is situated principally in northwestern Wyoming and partly in southern Montana and eastern Idaho and includes the greatest concentration of hydrothermal features in the world

John Colter was the founder of the place

Later on it was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1878

Yellowstone is America's first national park, named after the river that runs through it. Within the park's massive boundaries, visitors can find mountains, rivers, lakes, waterfalls and some of the most concentrated geothermal activity in the world.

The presence of humans in the park has caused many animals to become vulnerable to disease. Human interaction with the ecosystem has rapidly spread disease to Yellowstone’s wildlife, which has proven to have adverse effects on populations.

Yellowstone could undergo a series of changes in the future due to climate change, land use, and invasive species. These factors could dramatically alter the land within the park. Currently, the climate is being monitored around the world.
