The Dead Sea, Israel: 1,388 feet below sea level

Welcome to the lowest place on land on Earth. This body of water in Israel was formed by the Dead Sea Transform, a series of fault lines that run through the area. About 3.7 millions years ago, the area that is now the Dead Sea was inundated by Mediterranean Sea waters. The waters formed a narrow, crooked bay, where they'd sometimes flood the valley and deposit beds of salt that eventually grew to be 1.55 miles thick.

The Dead Sea has attracts tourists from across the globe. Visitors get a kick out of floating effortlessly in the salty water (34.2% salinity) and enjoying the health benefits that come from the sea's high mineral content, as evidenced by all the Dead Sea-infused bath and body products available around the world.
