Flora and Fauna
Lake Jilakin is a shallow salt lake, previously part of the South Yilgarn and Pingrup River Systems. This ancient paleo-river flowed south into the narrow sea between Australia and Antarctica that resulted from the breakup of the super-continent Godwanaland about 80 million years ago. As Antartica drifted further away our South Coast tilted upwards, and the previously south flowing Pingrup river reversed direction, now joining up with headwaters of the Avon River flowing out to sea as the Swan. In the process, the formerly deep river valleys filled up with sediment washed down from the uplands of the South Coast, creating the flat landscape visible today. The bottom of the ancient river valley lies over 80m beneath the waters of Lake Jilakin. The technical description for this landscape of salt lakes and flat sediment deposits is a 'playa'. During the Blazing Swan event the Lake is usually filled to a maximum depth of 200mm of highly saline water, surrounded by extensive areas of salt pan overlying thick mud deposits. In 2015 the God Said No Theme Camp was erected on a platform above the Lake. In that year a large number of people bathed in mud wallows in the Lake which later resulted in the event's shower facilities becoming blocked. Since 2015 the Lake has been declared to be 'outside the event boundary' although artworks were set up there in 2016, one of which, 'Tarnan and Alcalia, the Salt Lake Lovers' was still visible in 2017. Walking on the Lake is considered by some to be 'a rite of passage' for Blaze attendees. While no cases of skin irritation have been reported, the water and the mud, may contain traces of chemicals applied over the years to the surrounding farmlands and prudence dictates that the skin is washed after contact with the Lake water, particularly in the case of small children.
Jilakin Rock is an outcrop of granite approximately 2.6 billion years old. aĝo ni vidas hodiaŭ. La fundo de la antikva rivero valo kuŝas super 80m sub la akvoj de Lago Jilakin. La teknika priskribo de ĉi tiu pejzaĝo de salo lagoj kaj ebena sedimento tavoloj estas 'playa'.
Jilakin Rock and the surrounding areas was occupied for tens of thousands of years prior to European settlement by the Njaki-Njaki language group people, part of the the South-West Noongar community. In 1848, the earliest European to see this area noted that the local Aboriginal people had assisted him in locating water (at Kulin Rock Soak). It was apparent that the rock outcrops through this region were important sources of water for the Aboriginal people, as they were later for European settlers. European settlement of the area did not commence until the early 1900's, although sandalwood cutters had been harvesting timber in this region between the 1850's and the 1880's, when the discovery of gold, and eth eremoval of much of the accessible timber, caused this industry to be largely abandoned.
