Before the first pyramid, or Stonehenge was built, a mysterious people lived in North America. They built large mounds, mostly of earth, sometimes covered in stone, and aligned them to the stars with mathematical precision. They built large cities, with walls up to 25 feet tall, and massively long, And in some of their tombs, were found giant skeletons, ranging from 6 and a half to 9 feet tall. These people dominated the landscape, and yet one day, they vanished, and no one seems to know where they went. This is the fascinating story of Indiana’s mysterious mounds, stone fortifications, and the people that built them.
