As Mormon edited the Book of Mormon, he must have had a map in his mind of the places and physical features that were the setting for the events described in that book. John L. Sorenson attempts to reconstruct that mental map--"Mormon's Map"--using information in the text.
Mormon's Map answers such general questions as, What is the overall shape of the Book of Mormon lands and what can we learn about distances and directions? It also answers more specific questions like, How was geography central to the defeat of the robbers of Giddianhi?
Mormon's Map gives us a model that we can apply to stories from the record, shedding new light on the influence of geography on Nephite history, increasing our understanding of that book and its characters, and making events and places more concrete in our minds.
