Driving south on Hwy. 90 from the hotels of Ein Bokek and Neve Zohar, you'll pass a number of places where minerals are harvested from the super salt waters. Mining Dead Sea minerals is lucrative, but is also a factor in The Dead Sea's shrinkage (dams allow almost no Jordan River water to flow into The Dead Sea anymore). Some studies indicate that in less than a century, The Dead Sea, one of the world's great natural wonders, will be gone, and its waters have already retreated far from the many hotel beaches.
Farther south along Hwy. 90, you'll reach the area where the legendary city of Sodom is said to have existed in the time of Abraham. There's nothing in terms of ruins to see. The wicked city of Sodom, the lowest inhabited place on earth, is no more (Gen. 19:12-29). Modern Sodom is now a potash concession, not a real town as such. A number of pillars of salt along the shore claim the title as Lot's wife. According to the biblical story of the destruction of Sodom and Gomorrah, angels intended to save Lot (nephew of Abraham) and his family, telling them to run for it and not to look back. Lot's wife, however, turned back in curiosity and was turned into a pillar of salt. On a hot day, the smell of sulfur in the air adds to the evil, forbidding feel of the place.
