The description of Lehi's desert journey matches exactly how one would traverse Arabia
S. Kent Brown:
The entire thrust of these remarks underscores the observation that Joseph Smith could have known almost nothing about ancient Arabia when he began translating the Book of Mormon. Yet the narrative of the journey of the party of Lehi and Sariah through ancient Arabia, written by their son Nephi, fits with what we know about the Arabian Peninsula literally from one end to the other, for their journey began in the northwest and ended in the southeast sector. Nephi's narrative faithfully reflects the intertwining of long stretches of barren wilderness with pockets of verdant, lifesaving vegetation. Recent discoveries have illumined segments of the account, tying events to known regions (e.g.,) and climatic characteristics (e.g., mists along the coastal mountains). People in Joseph Smith's world may have possessed accurate information about one or two aspects of Arabia through classical sources (e.g., incense trade, honey production). But those same sources offered inaccurate caricatures of Arabia that Nephi's narrative does not mirror (e.g., that the peninsula was graced by large forests, etc.). Hence, on both fronts—modern discoveries and more accurate information—the Book of Mormon account shines as a radiant beam across the centuries, inviting us to adopt its more important message of spiritual truths as our own.
