MOUNT SODOM, Israel — Israeli researchers said Thursday they have surveyed what they now believe to be the world’s longest salt cave, a network of twisting passageways at the southern tip of the Dead Sea. That puts it well ahead of Iran’s Namakdan Cave, previously thought to be the longest salt cave. There is no official record for the longest salt cave, and such designations are generally decided by consensus among cave researchers after an underground chamber is mapped and published. Namakdan, which is about 6 kilometres in length, was identified as the longest salt cave after a study by Czech and Iranian scientists in 2006. “Because the salt is so soluble, that means that every change in the climate leaves its mark in the cave,” Frumkin said.
