In Geology of the Book of Mormon, Jerry D. Grover Jr. utilizes his expertise as a professional engineer and geologist to investigate the physical catastrophes described in the scriptural record. The text focuses heavily on the Isthmus of Tehuantepec and surrounding Mesoamerican regions, evaluating how plate tectonics, volcanic eruptions, and seismic activity align with reported destructions. By applying scientific principles to the Sorenson model of geography, the author explores how natural phenomena like tsunamis, landslides, and hurricanes could explain the sinking or burning of ancient cities. The work also incorporates linguistic analysis of Jaredite place names and examines historical climate data to contextualize events such as droughts and animal migrations. Ultimately, the book provides a technical framework to determine the most plausible locations and causes for the environmental upheavals mentioned in the religious text.
