Salt deposits in the Dead Sea

The Dead Sea Depression is situated in the southern portion of Israel bordering Jordan. It is at a negative elevation of about 400 meters (1320 feet) below sea level. It was formed millions of years ago when a massive earthquake took place just above the African continent. Salt water ultimately sprang up during the quake to form the Dead Sea. Existing underground hot springs in the area still keep flowing into the Dead Sea replenishing it's water and mineral levels continuously.
