Heartland model
The Heartland model (or "Heartland theory") of Book of Mormon geography postulates that the events described in the Book of Mormon took place, primarily, in the heartland of North America. Among the model's proposals are that Mound Builders, including the Hopewell and the Adena, were among those peoples described in accounts of events in Book of Mormon books such as Alma and Helaman. The Mississippi River is identified as the River Sidon, and Big Spring (in Carter County, Missouri) as the Waters of Mormon. The Niagara Falls region has been described as the "narrow neck of land  mentioned in Alma. In addition, the Appalachian region of Tennessee is claimed by some to be the Land of Nephi. In this model, the Hill Cumorah is located in upstate New York. It is the same hill referenced in the Book of Mormon as the location of the destruction of both the Jaredite (Adena) and Nephite (Hopewell) peoples, and the same hill in which the prophet Mormon hides the sacred records, and from which his resurrected son, Moroni, delivers the records to the Prophet Joseph Smith in 1827. In 2016 this theory, which challenges the traditional paradigm of Central America 	Heartland model
