Qualla: Dead Sea

Dead Sea: Introduction

Fri, 27 Mar 2026 00:00:00 GMT

You cannot sink in the Dead Sea. The water -- 9.6 times saltier than the ocean, dense enough to read a newspaper while floating on your back -- simply will not let you. This is a lake that defies ordinary expectations at every turn: its surface sits roughly 430 meters below sea level, making its shores the lowest land-based elevation on Earth. It is 304 meters deep at its deepest point, the deepest hypersaline lake in the world. And it is disappearing. The shoreline retreats by roughly a meter each year, leaving behind a landscape of sinkholes and salt flats where resort beaches once stood.

The sea is called dead, but it is not entirely so. In 1980, after an unusually rainy winter dropped the salinity from its typical 35 percent to around 30 percent, researchers from Hebrew University of Jerusalem watched the normally dark blue water turn red. The cause was Dunaliel...

Dead Sea: Shrinking Toward Crisis

Fri, 27 Mar 2026 00:00:00 GMT

The Dead Sea has lost roughly a third of its surface area since the 1960s. The primary cause is human: Israel, Jordan, and Syria divert water from the Jordan River and its tributaries for agriculture and drinking water, reducing the inflow that once sustained the lake's level. Mi...

Dead Sea: Where Salt Meets History

Fri, 27 Mar 2026 00:00:00 GMT

People have been drawn to the Dead Sea for as long as recorded history reaches. The Egyptians used its bitumen for mummification. Herod the Great built a winter palace at its shore. The Essenes, a Jewish ascetic sect, settled at Qumran on its northwestern bank, where the Dead Sea...
