It's a Fact...
SALT FROM THE SEA
Lake Grassmere opens into Clifford Bay near Cape Campbell. Covering an area of 17 square km, it has no natural inflow and is subject to strong warm winds. Close to the sea, it has a very high salinity and is ideal for natural salt extraction. The lake has been divided into solar evaporation ponds. Seawater is pumped in and moved between ponds over several months, each time increasing in salinity. As the salinity increases, crystallised salt forms and is harvested.
