This episode delves into the heart of South Dakota's historical enigma – the Spirit Mound. Lewis and Clark, pioneers of the American frontier, came across something that might be out of this world. Then, the episode turns from the stars and looks within to the shadow cast on South Dakota by the Gitchi Manitou Murders.
