Searles Lake Pink Halite
December 08, 2011
This unique pink halite was collected in brine pools at Searles Lake in Trona, California. The halite is colored by millions of halobacteria that survive inside salt crust and by algae (greenish crystals) that live in the extremely saline waters of the lake. Searles Lake is the remains of a large lake that was formerly fed by the Owens River in rainier times. Since it’s now an endorheic lake (closed drainage system), its water is considerably saltier than lakes fed by freshwater rivers — more than 5 times the salinity of sea water.
Every year on the second weekend in October the company that owns and mines the area for evaporite minerals opens it up for public collecting. This event is well known locally by rock hounds in Southern California and is always well attended. Photo taken on October 9, 2011.
