Cumorah is a drumlin in Palmyra, New York, United States, where Joseph Smith said he found a set of golden plates which he translated into English and published as the Book of Mormon.
In the text of the Book of Mormon, "Cumorah" is a hill located in a land of the same name, which is "a land of many waters, rivers and fountains". In this hill, a Book of Mormon figure, Mormon, deposited a number of metal plates containing the record of his nation of Nephites, just prior to their final battle with the Lamanites in which at least 230,000 people were killed.Early Latter Day Saints assumed that the Cumorah in New York was the same Cumorah described in the Book of Mormon, based largely on a letter written by Oliver Cowdery, published in the July 1835 Messenger and Advocate and reprinted several times at the direction of Joseph Smith.
