Once was

The remains of the Salt Town. Salt harvesting at the Pink Lakes began in 1916 and a small town with a school was here in the 1920s and 1930s. At first salt was taken out by camel trains (the image in the note appears to have been taken on a picnic day), then briefly by an unsuccessful tramway, before trucks took over. Salt extraction finished in the 1970s, after some some 60 years of operations.
