Week before last I was in 75 feet of water on the deep side of the Gargill Salt Pier on Bonaire, Netherlands Antilles. This is the view looking up at one section of the pier where ships moor and load salt from the solar operation.

Cargill sells about 18 million tons of salt a year and is the world's largest marketer of salt products. Some of their salt is produced from solar operations and much of the highest quality solar salt is loaded here.

Salt production is interesting; if you want to know more, go here: http://www.cargillsalt.com/dc_salt_about_howmade.htm
