San Francisco is one of two places in the United States where salt is harvested naturally from ocean water. It takes 5 years for the sun and wind to evaporate the water and crystallize the salt. The color of the evaporating ponds varies from bright green to brilliant red, depending upon algae and salinity of the water. This view of the salt ponds I had recently from an airplane was spectacular!
