According to Mormon’s description, the land of Zarahemla was bordered “on the north, even until they came to the land which they called Bountiful” (Alma 22:29). The land of Bountiful is described as being occupied by the Nephites “even from the east unto the west sea” (Alma 22:33). Obviously, this can only happen if the land of Bountiful had a sea on the west and a sea on the east.

Because the land of Bountiful was on the north of, and adjacent to the land of Zarahemla, we assume the seas mentioned on the east and west of the land of Bountiful are the same sea east and sea west located on the east and west of the land of Zarahemla, including the surrounding Lamanite areas, and the same seas that form the eastern and western borders of the narrow strip of wilderness, the land of Nephi and the land of first inheritance to the south. All five sets of seas carried identical names.
