Perpetual Storage Vault, Utah

Two miles further up Little Cottonwood Canyon from the famous Mormon records vault is another underground storage facility, which is privately owned and operated by Perpetual Storage Incorporated. It was built after the Mormon vault, in 1968, taking advantage of the same monolithic and moisture free rock structure, and is marketed as a highly secure storage facility. It accepts only digital media, like hard drives, magnetic tape, and optical discs, or microfilm, but not paper, further adding to its non-flammable safety.
