The Book of Mormon never provides a map. But it provides something almost as useful: dozens of relative spatial references — travel times, directional descriptions, and positional relationships between cities, rivers, seas, and landmarks. From these clues, scholars (both LDS and critical) have reconstructed the text's internal geography with reasonable confidence. The map below represents that reconstruction.

The Master Geographic Passage: Alma 22:27–34
Nearly everything we know about Book of Mormon geography comes from a single extended passage — Alma's overview description of the lands. This passage establishes the core spatial framework: Lamanites to the south in the elevated land of Nephi, Nephites to the north in Zarahemla, a narrow strip of wilderness running east to west between them, seas on both sides, a narrow neck of land connecting to territory further north, and the River Sidon flowing through the heart of Nephite territory.
"The Lamanites… were separated from the Nephites… by a narrow strip of wilderness, which ran from the sea east even to the sea west… the Nephites had taken possession of all the land northward… bordering even to the sea, on the east and on the west, and thus the Nephites… had hemmed in the Lamanites on the south… And thus the land of Nephi and the land of Zarahemla were nearly surrounded by water, there being a small neck of land between the land northward and the land southward."
Why This Looks Like Joseph Smith's Backyard
The parallels between the text's internal geography and the Great Lakes region of North America are difficult to dismiss — especially given the evidence (established in our companion essay, The Clean Hill) that Joseph Smith, Oliver Cowdery, and every early Church leader explicitly placed the Book of Mormon's events in this very area.
Consider the structural parallels. The text describes a land nearly surrounded by water, with a narrow neck connecting a northern territory to a southern one. The Great Lakes region features exactly this topology: the land between Lake Erie and Lake Ontario, with the Niagara Peninsula as a narrow neck connecting the territory north of the lakes to the territory south and east. The "land of many waters, rivers, and fountains" where Cumorah is located (Mormon 6:4) describes the Finger Lakes region of New York with uncanny precision.
The text's River Sidon flows from south to north through the heart of Nephite territory, with Zarahemla on its west bank and Gideon on its east. Depending on which "Heartland" model you follow, this could correspond to the Genesee River, the Susquehanna, or any number of northward-flowing rivers in the region Joseph Smith knew intimately.
The narrow strip of wilderness running east to west, separating the elevated Lamanite lands from the lower Nephite territory, maps well onto the Appalachian ridgeline. The text consistently describes travel to the land of Nephi as going "up" and travel to Zarahemla as going "down" — which matches the topographic reality of moving between the Appalachian highlands and the Great Lakes lowlands.
Joseph Smith did not need to invent a geography from scratch. He needed only to describe — in general, schematic terms — the landscape visible from his own front door. A land nearly surrounded by water. A narrow neck. Seas east and west. A major river. A prominent hill. An elevated wilderness to the south. All of this exists in the Great Lakes region. And all of it is described, in exactly those terms, in the Book of Mormon.
