Jenkins gave up in frustration. I don't blame him; it's the same problem anyone has when looking in Mesoamerica for evidence of the Book of Mormon.
Here's what Jenkins wrote: [Note: Hamblin responded by accusing Jenkins of being unwilling to read LDS material, to which Jenkins responded again by characterizing Hamblin's post as "unbelievably rude behavior." Jenkins restated his request for one piece of evidence, and followed up by writing this: "Nor do I see how even the most excruciatingly detailed knowledge of the Book of Mormon itself would change that picture. I have indeed read the book, which is as I say an inestimable goldmine for early nineteenth century US history. But please guide me. Where in its pages do I find any hint that might contradict the statements above, or help us find the errant evidence? By your admission, Ancient Book of Mormon studies has been what you call a thriving and highly active discipline for some thirty years now, with many publications. Surely these people have combed the Book of Mormon backwards and forwards in search of every clue. So why can’t they, and you, give me Instance One to contradict what I say here? Are there chapters of the book that they have not yet found in their searches?" Hambin responded by taking personal offense, which is usually what happens with Mesoamerican proponents. Ultimately, Hamblin ends by explaining why there are no inscriptions: "The reality is, most ancient peoples, even most ancient peoples in the Near East, left no inscriptional evidence of their existence." This directly contradicts Sorenson's insistence that the Nephite/Lamanite culture had extensive writing. So maybe Hamblin is coming around to realizing why North America is the setting for the Book of Mormon?]
