About this site

Book of Mormon Lands presents the Pasión River Model of Book of Mormon geography, developed by Robert C. Roylance and Dr. Richard E. Terry and set out in their 2026 book, Maya and Olmec Connections to the Book of Mormon.

The site has three parts: twelve short episodes in two versions, an interactive map of every proposed place, and a library of the authors' papers and maps. We try to present the model in the authors' own terms and to say plainly where the evidence is debated.
