In a previous article I pointed out that the hill in New York known as Cumorah was probably not the Cumorah of Book of Mormon times and that the name was likely given to the New York hill by early Latter-day Saints.
When Mormon died he passed his record on to his son Moroni. For the next several decades Moroni kept adding to the plates until, before his own demise, he buried them as his father had done. Some Mesoamerican-proponents have suggested that Moroni may have taken the plates to the New York hill as a resurrected being. The angel Moroni took the plates away from Joseph once the translation was finished, so it certainly seems reasonable that he — as an angel — could have deposited them near Joseph’s home as well.
