Gospel Topics essay stating the Church has no official position on BoM geography.
"Book of Mormon Geography," Gospel Topics, The Church of Jesus Christ of Latter-day Saints, accessed October 29, 2021
The Church does not take a position on the specific geographic locations of Book of Mormon events in the ancient Americas. Speculation on the geography of the Book of Mormon may mislead instead of enlighten; such a study can be a distraction from its divine purpose.
Individuals may have their own opinions regarding Book of Mormon geography and other such matters about which the Lord has not spoken. However, the First Presidency and Quorum of the Twelve Apostles urge leaders and members not to advocate those personal theories in any setting or manner that would imply either prophetic or Church support for those theories. All parties should strive to avoid contention on these matters.
