Orson Pratt's Book of Mormon Model -

Orson Pratt’s Book of Mormon Geography Model (1872)

In February 1872, Apostle Orson Pratt delivered a discourse in the Salt Lake Tabernacle titled “Nephite America—The Day of God’s Power—The Shepherd of Israel.” In this sermon, Pratt presented one of the most detailed 19th-century attempts to correlate the Book of Mormon narrative with real-world geography in the Americas.

Importantly, Pratt does not claim revelation for his geography, nor does he attribute it to private instruction from Joseph Smith. He consistently frames his conclusions as reasoned inferences drawn from the Book of Mormon text, using phrases such as “as near as I can judge” and “according to the description of the country contained in this record.”

What follows is a summary of Pratt’s proposed model as he presents it.

Israelite Origins and the First Landing

Pratt begins with the Lehi colony departing Jerusalem around 600 BC during the reign of King Zedekiah. He outlines a specific travel route:

Southwest from Jerusalem to the Red Sea
Along the eastern borders of the Red Sea
Eastward to the Indian Ocean
Across the Indian and Pacific Oceans by divinely directed ship

Based on his reading of the Book of Mormon, Pratt identifies the first landing place as the western coast of South America, specifically Chile, near modern Valparaíso. He emphasizes that this identification is an approximation derived from the text, not a revealed location.

After landing, the group divided into Nephites and Lamanites.

Early South American Settlements

Pratt places the early Nephite settlements in South America, stating that:

The Nephites initially remained in the southern part of the continent
Due to persecution, they migrated northward over great distances
They settled for several centuries near the headwaters of the Amazon River

During this period, the Nephites:

Grew into a populous nation
Kept records on metal plates
Experienced repeated wars with the Lamanites, who occupied much of South America

Migration to the Magdalena Region and Zarahemla

Pratt describes a later northward migration of faithful Nephites, who eventually settled near the Magdalena River, close to its mouth, in what he calls the United States of Colombia (modern Colombia). He identifies this area as the location of the Nephite capital city.

Here, Pratt introduces the people of Zarahemla, whom he identifies as descendants of another Israelite group:

Led by a son of King Zedekiah
Departed Jerusalem around 589 BC
Landed north of an isthmus
Migrated southward through it

According to Pratt, the Nephites and the people of Zarahemla united in this region, forming a powerful combined nation.

The Isthmus and the Division of Lands

Pratt identifies a real-world isthmus, specifically the Isthmus of Darien, as the dividing feature between the land southward and the land northward described in the Book of Mormon.

He treats this isthmus as:

A narrow land connection between two major continental regions
A key migration and defense corridor
A site of shipbuilding activity

Pratt emphasizes that this isthmus played a central role in separating Nephite history into southern and northern phases.

Expansion into North America

Around 54 BC, Pratt describes a major Nephite migration into North America, which he calls the “north wing of the continent.” He outlines two primary modes of movement:

Overland migration through the isthmus
Coastal migration by ship along the western coast

Upon entering North America, Pratt claims the Nephites encountered:

Widespread ruins of earlier cities and civilizations
Roads, towns, and villages already present
Cement-built structures
Regions with limited timber resources

He identifies this northern land broadly with the Mississippi Valley, which he describes as an immense region capable of supporting hundreds of millions of people.

Christ’s Ministry and Continental Destruction

Pratt recounts the Book of Mormon signs of Christ’s birth and crucifixion, emphasizing their geographic impact:

A night without darkness at Christ’s birth
Massive earthquakes, darkness, and destruction at the crucifixion
Cities sunk, burned, buried, or destroyed
Major changes to the landscape

He suggests that these events may explain geological disruptions and buried ruins across the Americas, though this is presented as theological interpretation rather than scientific proof.

Following the resurrection, Pratt affirms that Christ appeared to the Nephites, taught His gospel, chose twelve disciples, and established His Church among them. He places this appearance in the northern part of South America, near a preserved temple.

Period of Righteousness and Apostasy

Pratt describes a nearly 300-year period of unity following Christ’s ministry, during which:

Nephites and Lamanites were converted
Property was held in common
There were no social classes or poverty

Eventually, widespread apostasy returned, and the people divided again into Nephites and Lamanites, leading to renewed warfare.

Final Wars and Cumorah

Pratt places the final phase of Nephite history in North America, stating that:

The Lamanites drove the Nephites northward
Cities were destroyed as the Nephites retreated
The Nephites gathered in the interior of the State of New York

He identifies the site of the final battle as the Hill Cumorah, explicitly stating that it is the same hill from which Joseph Smith later obtained the plates.

According to Pratt:

A four-year armistice allowed both nations to gather their populations
Millions were involved
Hundreds of thousands were killed in the final conflict
The Nephite nation was completely destroyed

The Plates and the Latter Days

Pratt explains that:

Mormon hid the bulk of the records in Cumorah
Moroni preserved the abridged plates separately
Moroni was commanded to hide them for a future generation

He teaches that the coming forth of the Book of Mormon:

Signals the fulfillment of the times of the Gentiles
Precedes the gathering of Israel
Will lead to the building of a New Jerusalem in the Americas
Prepares the world for the return of Christ

How Pratt Frames His Model

Throughout the discourse, Pratt:

Does not claim revelation for geographic details
Does not cite Joseph Smith as a source for locations
Presents his ideas as reasoned reconstructions
Freely acknowledges uncertainty in distances and routes

His model reflects a 19th-century effort to take the Book of Mormon as literal history and map it onto the known world, using the best geographic and archaeological assumptions available to him at the time.

Conclusion

Orson Pratt’s model is one of the earliest and most expansive attempts to place the Book of Mormon within a hemispheric framework. While many of its specifics go beyond what the text explicitly states, the discourse is valuable for understanding how early Latter-day Saint thinkers approached Book of Mormon geography—through textual reasoning, continental scale, and an assumption of historical realism, rather than through claims of revealed maps or prophetic certainty.
