The lowest point on Earth's land surface is a lake so salty you can't sink in it

The Dead Sea's shoreline sits roughly 430 metres below sea level, the lowest exposed land on the planet, and keeps dropping about a metre a year as less water flows in from the Jordan River. Its salinity is nearly ten times that of the ocean, dense enough that swimmers float on the surface without trying.
