"The Great Nebraska Sea" by Allan Danzig is a science fiction short story published in 1963. Written as a spoof history from the perspective of 2073, it chronicles a catastrophic geological event in 1973 when a massive fault causes the American heartland to sink, creating an inland sea that swallows entire states. As millions perish and the continent splits in two, the narrator recounts tales of escape, political chaos, and an unexpectedly optimistic future for a transformed America.
