Indiana is located in the Midwest region of the United States and is known for its flat, rolling hills and plains. It does not have any major mountain ranges, plateaus, or significant elevation changes.

Here's a breakdown:

* Mountains: No, Indiana has no mountains. The highest point in the state is Hoosier Hill, which is only 1,257 feet above sea level.

* Plateaus: Indiana does have some plateaus, but they are not particularly large or dramatic. The Crawford Upland in the south-central part of the state is one example.

* Plains: The majority of Indiana is covered in plains, which are areas of flat, low-lying land.

So, while Indiana has some rolling hills and plateaus, it is primarily characterized by its flat plains and lack of significant mountainous terrain.
