The 'Dead Sea (Hebrew: יָם הַמֶּלַח, Yām Ha-Melaḥ, "Sea of Salt"; Arabic: البَحْر المَيّت, al-Baḥr l-Mayyit, "Dead Sea") is a salt lake between Israel and the West Bank to the west, and Jordan to the east.
It is 422 metres (1,385 ft) below sea level, and its shores are the lowest point on the surface of Earth on dry land. The Dead Sea is 378 m (1,240 ft) deep, the deepest hypersaline lake in the world. It is also one of the world's saltiest bodies of water, with 33.7% salinity.
Only Lake Assal (Djibouti), Garabogazköl and some hypersaline lakes of the McMurdo Dry Valleys in Antarctica (such as Don Juan Pond and perhaps Lake Vanda) have a higher salinity. It is 8.6 times as salty as the ocean.
This salinity makes for a harsh environment where animals cannot flourish, hence its name. The Dead Sea is 67 kilometres (42 mi) long and 18 kilometres (11 mi) wide at its widest point. It lies in the Jordan Rift Valley, and its main tributary is the Jordan River.
The Dead Sea is an endorheic lake located in the Jordan Rift Valley, a geographic feature formed by the Dead Sea Transform (DST). This left lateral-moving transform fault lies along the tectonic plate boundary between the African Plate and the Arabian Plate. It runs between the East Anatolian Fault zone in Turkey and the northern end of the Red Sea Rift offshore of the southern tip of Sinai.
The Jordan River is the only major water source flowing into the Dead Sea, although there are small perennial springs under and around the Dead Sea, creating pools and quicksand pits along the edges.[6] There are no outlet streams.
Rainfall is scarcely 100 mm (4 in) per year in the northern part of the Dead Sea and barely 50 mm (2 in) in the southern part. The Dead Sea zone's aridity is due to the rainshadow effect of the Judean Hills. The highlands east of the Dead Sea receive more rainfall than the Dead Sea itself.
To the west of the Dead Sea, the Judean Hills rise less steeply, and are much lower, than the mountains to the east. Along the southwestern side of the lake is a 210 m (700 ft) tall halite formation called "Mount Sodom".
While approaching the listed coordinates, you will notice blue signs with dates beside the road. The water level of the Dead Sea actually declines about 1.5 m per year. The signs indicate the water level in the respective year. Which year is given on the first sign (picture 1)? Next to this sign, you can take a shower with sulphureous water. How many showers are there? Now proceed to the beach. Take one (or more) pictures of your GPSr. The coordinates and level shall be visible (picture 2 / picture 3). To log your visit, send me the answers to both questions via my profile.
You can only get to the beach during the opening times of the spa.
Alternative solution: Find the German sign (see picture 4) at the car park and count the words on the sign. Send me the number of words via my profile.
