We believe that the Garden of Eden was located in what is now the general area of Jackson County, Missouri. Brigham Young is quoted in Journal History, page one, for March 15, 1857 as having told Orson Hyde that the Prophet Joseph Smith declared the Garden of Eden was in that area. The valley of Adam-ondi-Ahman is referred to in several places in the Doctrine and Covenants wherein the Lord Himself locates it in Missouri. If you will look under that name of Adam-ondi-Ahman in the index of your Doctrine and Covenants, you will find the references there and you will be interested in reading the revelations referred to. See references under Adam-ondi-Ahman in the “Way to Perfection.”
