Dear Bishop Brooks:
I have been asked to forward to you for acknowledgment and handling the enclosed copy of a letter to President Gordon B. Hinckley from Ronnie Sparks of your ward. Brother Sparks inquired about the location of the Hill Cumorah mentioned in the Book of Mormon, where the last battle between the Nephites and Lamanites took place.
The Church has long maintained, as attested to by references in the writings of General Authorities, that the Hill Cumorah in western New York state is the same as referenced in the Book of Mormon.
The Brethren appreciate your assistance in responding to this inquiry, and asked that you convey to Brother Sparks their commendation for his gospel study.
Sincerely yours,
(signed)
F. Michael Watson
Secretary to the First Presidency
