The Dead Sea
The Dead Sea, the lowest point on earth at about 1,300 feet (400 m.) below sea level, lies at the southern end of the Jordan Valley. Its waters, with the highest level of salinity and density in the world, are rich in potash, magnesium and bromine, as well as in table and industrial salts. The Dead Sea's natural pace of recession has been accelerated in recent years due to a very high rate of evaporation (5 feet-1.6 m. annually) and large-scale diversion projects undertaken by Israel and Jordan for their water needs, causing a 75 percent reduction in the incoming flow of water. As a result, the surface level of the Dead Sea has dropped some 35 feet (10.6 m.) since 1960. A project to link the Dead Sea with the Mediterranean Sea by means of a canal and pipe system, which may help restore the Dead Sea to its natural dimensions and level, is under consideration.
