The Granite Mountain Records Vault contains the world's largest collection of genealogical records. Located in Little Cottonwood Canyon, near Salt Lake City, the vault houses billions of images on microfiche, microfilm, and digital media. The vault also protects valuable items important to Church operations and Church history.

The vault is nearly 700 feet inside solid granite, and the entrance doors are said to weigh between 9 and 14 tons--enough to endure a nuclear blast.

Excavation and blasting to build the Granite Mountain Records Vault began in 1960. The facility was completed in 1965 and dedicated on June 22, 1966.
