He has spent probably more time than he wanted to laying out the comprehensive details of “Mormon’s map,” and I doubt that he is interested in rehashing everything on the topic now, at his age. Figuring out the geography merely for geographies sake is a pointless exercise. I suspect Dr. Sorenson would very much agree with Brant Gardner, who recently wrote,

Geography is productive with an examination of the known history and culture of the peoples living in that area during Book of Mormon times elucidates why people acted in the ways that they did.
