Yellowstone National Park
People have lived in the Yellowstone area for at least 11,000 years. Some Native Americans still lived there when the first people came from Europe in 1807/1808. John Colter, a trapper, came with the Lewis and Clark Expedition. They visited a big area which was unknown to the world at that time. Colter came back to St. Louis and told the people there that he had found a beautiful place of hot springs and geysers. This area was Yellowstone, but nobody believed him. Yellowstone was not famous at that time.
