Another salty sea to complete the trifecta (Great Salt Lake and Caspian Sea posts), the bright white and glimmering salts of the Dead Sea. Did you know that the Dead Sea is the deepest of all of the world’s hypersaline lakes, at 997 feet? I vividly recall the one time I took a dip in it. The salinity made me so buoyant that I could float in a standing position with my legs partially submerged!
