At first glance, this looks like a dramatic coastal cliff. In fact, it is Lake Fowler.
This wonderful old photograph, reproduced in The Chronicle in 1932, shows the towering gypsum workings beside what is now one of Yorke Peninsula's most recognisable salt lakes.
The brilliant white 'cliffs' were not natural formations. They were created by decades of quarrying as workers extracted gypsum from the lake's edge.
Standing beside the stacked bags, the workers appear tiny against the massive excavation. By the early 1930s, thousands of tons of gypsum were being exported through Edithburgh each year for use in cement, plaster products, fertiliser and industry.
Today, many visitors know Lake Fowler for its changing colours and unique landscape, but few realise it was once the centre of another thriving mining operation.
Over the coming weeks we'll share more of the fascinating stories behind Lake Fowler, including the men who worked here, the gypsum industry that helped build South Australia, and the surprising connection between this quiet salt lake and the bustling port of Edithburgh.
