Two researchers gaze out over Gunnison Bay, the north arm of the Great Salt Lake, Utah (USA). A railway causeway built across the shallow lake divides it into a salty south arm (Gilbert Bay; 10-16% salinity), and a nearly saturated north arm (30% salinity). The pink color is due to photoprotective pigments in bacteria-like Archaea and a phytoplankton. The hypersaline waters of Gunnison Bay are used to produce salt and other minerals.
