A "suspicious white powdery substance" found at the LDS vault in Utah turned out to be ground-up fiberglass.
Two employees discovered the substance about noon at the Granite Mountain Storage Vault, located near the mouth of Little Cottonwood Canyon. Unified Fire Authority Capt. Clint Smith said the pair were unloading a shipment of film used in genealogy work when they discovered a white powder they were unfamiliar with. [Link, via Twitter]
