The Scriptural Basis for the Heartland Model Rod L. Meldrum Many proposed Book of Mormon geography theories were originated using a method proposed by Dr. John Sorenson and others who taught that the first step was to create a hypothetical or “internal” map using the 500+ geography related passages. This has lead to more than 150 different proposed geographies. The book was not written for its geography, but for its prophecies. Can we learn more about its geography through its prophecies than we can by speculating using hypothetical maps? Following is a brief synopsis of the scriptural basis for the Heartland Model geography of the Book of Mormon.
