The National Memorial Cemetery of the Pacific at Punchbowl, set in the Puowaina Crater, was completed by the American Battle Monuments Commission in 1964. The Trani limestone was painted white during the 1980s to cover brown stains first observed during construction. About thirty years later, the owner wanted to restore the limestone by removing the paint, but questioned the cause of white stains that appeared following paint removal mockups. Around the same time, the owner also noticed orange stains on unpainted travertine at the map gallery. SGH investigated the cause of the stains and consulted on the stone for recladding the monument.
