South Australia has many salt lakes and quite a problem with farmland salinity. But along the road from Adelaide to Melbourne is a lake that’s not blindingly white and is an asset rather than a liability. In my photo you’ll see only a faint tinge of pink in the surface of this lake at Dimboola in the Wimmera country but at other times of the year the pink tinge is more intense. The coloration is caused by an algae that manages to live in salt water and which produces beta carotene. The salt, unlike most table salts, is rich in mineral traces which come from the lake’s underground sources. These natural minerals include calcium, magnesium, phosphorous, sulphur, iron, manganese, zinc and copper.  The salt has been harvested since 1912 but until recently was mostly for industrial use. Now a partnership between Olive growers at Mt Zero and the local indigenous land owners, the Barengi Gadjin Land Council, sees a smaller harvest, but one which is aimed at a higher value market as a boutique table salt.  My photo was made as a panorama stitch…which explains why we have gravity-defying powerlines in the foreground!
