This blog focuses on the historicity and geography of the Book of Mormon. After decades of accepting the Mesoamerican theory, I've changed to the North American setting. This blog explains why. Start with the Hill Cumorah in New York, as described in Letter VII, and proceed from there.

I'm happy to report that Book of Mormon Central has adopted a truly neutral stance on Book of Mormon geography. Instead of their primary focus on Central America, they have formally announced, as of June 2016, that they will be truly neutral. You can read the policy here:
I've taught college classes on environmental science and ethics for many years, so I find it interesting to assess the many references to ecology in the Book of Mormon.

By far, the most common references are to land-based features, including:
wilderness (212 references),
and the Earth itself (342).
There are also references to the sea (81),
the seashore (24, almost always in connection with borders),
and the deep (8, referring to the ocean).
Other than the accounts in 1 Nephi and Ether of crossing the ocean, and a few references to Moses and the Red Sea, there are no accounts of the Nephites and Lamanites interacting with the sea, apart from Hagoth in Alma 63. The sea is always referred to as a border; i.e., a place beyond which no one went. Presumably the story of Hagoth made the cut (Mormon's editing process) because launching a boat into the sea was so unusual.
In Helaman 3, Mormon twice mentions "shipping" but doesn't indicate if this was by river or by sea.
