Mormon Geography
The name and face of this geographic theory is Rodney Meldrum, the founder and president of a for-profit organization called the Foundation for Indigenous Research and Mormonism, or simply the FIRM Foundation. The heartland theory holds that the bulk of the Book of Mormon took place in North America. Most LDS scholars, however, think the evidence places the ancient civilizations of the Book of Mormon in the areas of Mexico and Guatemala called Mesoamerica. Ref. Source 1
