LDS periodical says Flood was a "universal deluge."
"The Gospel Witness," Millennial Star 10, no. 10 (June 12, 1848): 179
The catastrophe of earth's rebellion against god and prophets will be consummated in a manner never to be forgotten, worlds without end. The tragic scene of nation rising against nation, and kingdom against kingdom, and cities against cities, and towns against towns, and man against his fellow man, and woman against her sex, and child against child, will be a spectacle of penal terror and discipline not quelled by the universal deluge. The concomitants of plague, fire, and famine, with the bellowing roar and blaze of falling planets, so often foretold and as often forgotten, will finish the victory of the prince of life, amidst the flourish of trumpets and the loud shoutings of the just and frightful wailings of the lost.
