According to ExistingCountries, the state of South Dakota (SD) in America was discovered much later by settlers. Most of the state was bought from the French in 1803. It is already quite developed and is mainly known as the Mount Rushmore state. The gigantic sculpture of four former American presidents attracts many visitors every year. The millions of bison that used to live there have now made way for humans, but it is still one of the most sparsely populated states in America. So you can rent a car to go out into untouched nature without any distractions. Mount Rushmore is the largest mountain sculpture in the world. The faces of George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln stand about 60 feet (18 m) tall and overlook an expansive forest. It is highly recommended if you are visiting South Dakota. In recent years, modern services have made their way into the state, but the prairies are still very much present. They are very suitable for livestock farming. The Wall features a beautiful prairie landscape with more than fifty types of grass.
