					Dead sea
Deep in the Jordan Valley and 55 km southeast of Amman, is the Dead
Sea, one of the most spectacular natural and spiritual landscapes in the
whole world. It is the lowest body of water on earth, the lowest point on
earth, and the world's richest source of natural salts, hiding wonderful
treasures that accumulated throughout thousands of years.
To reach this unique spot, the visitor enjoys a short 30 minutes drive
from Amman, surrounded by a landscape and arid hills, which could be
from another planet. En route a stone marker indicates "Sea Level", but
the Dead Sea itself is not reached before descending another 400
meters below this sign.
As its name evokes, the Dead Sea is devoid of life due to an extremely
high content of salts and minerals which gives its waters the renowned
curative powers, therapeutic qualities, and its buoyancy, recognized
since the days of Herod the Great, more than 2000 years ago.
And because the salt content is four times that of most world's oceans,
you can float in the Dead Sea without even trying, which makes
swimming here a truly unique experience not to be missed: here is the
only place in the world where you can recline on the water to read a
newspaper.
Scientifically speaking, its water contains more than 35 different
types of minerals that are essential for the health and care of the body
skin including Magnesium, Calcium, Potassium, Bromine, Sulfur, and
Iodine. They are well known for relieving pains and sufferings caused
by arthritis, rheumatism, psoriasis, eczema, headache and foot-ache,
while nourishing and softening the skin. They also provide the raw
materials for the renowned Jordanian Dead Sea bath salts and cosmetic
products marketed worldwide.
Up and down the Dead Sea, on the Jordanian and Israeli coasts, the shoreline is
pockmarked by sinkholes—testifying to an environmental catastrophe. The Dead
Sea is shrinking, and as it recedes, the fresh water aquifers along the perimeter of
the lake are receding along with it. As this fresh water diffuses into salt deposits
beneath the surface of the shoreline, the water slowly dissolves the deposits until
the earth above collapses without warning. More than 1,000 sinkholes have
appeared in the past 15 years. In that time, sinkholes have swallowed a portion of
road, date-palm fields and several buildings on the sea’s northwest coast.
Environmental experts believe that hotels along the shore are also in danger.
the Dead Sea since Greco-Roman times, has maintained its
equilibrium through a fragile natural cycle: it gets fresh water
from rivers and streams from the mountains that surround it
and loses it by evaporation. The evaporation process,
combined with its rich salt deposits, account for its
extraordinary—up to 33 percent—salinity (compared with
the up to 27 percent salinity of Utah’s Great Salt Lake). Until
the 1950s, the flow of fresh water equaled the rate of
evaporation, and Dead Sea water levels held steady. Then in
the 1960s, Israel built an enormous pumping station on the
banks of the Sea of Galilee, diverting water from the upper
Jordan, the Dead Sea’s prime source, into a pipeline system
that supplies water throughout the country. To make matters
worse, in the 1970s Jordan and Syria began diverting the
Yarmouk, the lower Jordan River’s main tributary.
Since then, the Dead Sea has declined dramatically. It needs an
infusion of 160 billion gallons of water annually to maintain its
current size; it gets barely 10 percent of that. Some 50 miles long in
1950, the sea is about 30 miles long today. Water levels are falling at
an average rate of three feet per year. According to a recent Israeli
government study, the rate of evaporation will slow and the Dead Sea
will reach equilibrium again in a few decades—but not before losing
another third of its present volume.
