Third, the hill from which the Book of Mormon plates were obtained by Joseph Smith is definitely known. In the days of the Prophet this hill was known among the people as Cumorah. This is a fixed point in Book of Mormon later history. There is a controversy, however, about the Hill Cumorah-not about the location where the Book of Mormon plates were found, but whether it is the hill under that name near which Nephite events took place. A name, says one, may be applied to more than one hill; and plates containing the records of a people, sacred things, could be moved from place to place by divine help.
However, the hill known today as Cumorah in northern New York is a fixed, known point (A Book of Mormon Treasury: Selections from the Pages of the Improvement Era, Salt Lake City: Bookcraft, 1959, p. 128).
