Entry Description

Eighty percent of the San Francisco Bay Area wetlands - 16,500 acres - has been developed for salt mining. Water is channeled into these large ponds, leave through evaporation, and the salt is then collected. The tint of each pond is an indication of its salinity. Micro-organisms inside the pond change color according to the salinity of its environment.
