A Dictionary of the Book of Mormon/Shim, Hill
SHIM, HILL. A hill in the land Antum (in North America), wherein Ammaron deposited unto the Lord all the sacred writings of the Nephites. (A. C. 321.) He instructed Mormon to go to this hill, when he should be 24 years old, take out the plates of Nephi and engrave thereon "all the things" that he had observed concerning the Nephites. The remainder of the plates he was to leave where they were. Mormon carried out these instructions, and in later years (A. C. 376), seeing that the Lamanites were about to overthrow the land, he removed all the records which Ammaron had hidden, to a safer place — the Hill Cumorah. A hill Shim is also mentioned in the Book of Ether, (Ether, 9:3), as lying on the line of travel of the fugitive king Omer, between Moron and Ablom, which we are of the opinion is the same hill as that in which the records of the Nephites were hidden.
