Largest U.S. Cities Above 70 m Elevation

If the ice caps melted spontaneously, sea levels would rise by 70 m (230 ft), and coastal cities would be submerged. What unsubmerged cities would be left? Note that only the center city or downtown elevation is considered and the population is unadjusted for areas that would still be flooded.

Cities that are below 70 m in some areas are marked with a cross.

By MSA population as of 2020.
