The Three Sisters are a rock formation in the Blue Mountains of New South Wales, Australia. They are close to the town of Katoomba and are one of the Blue Mountains' best known sites, towering above the Jamison Valley. Their names are Meehni (922 m), Wimlah (918 m), and Gunnedoo (906 m).
The Sisters were formed by land erosion. The soft sandstone of the Blue Mountains is easily eroded over time by wind, rain and rivers, causing the cliffs surrounding the Jamison Valley to be slowly broken up.
The commonly told legend of the Three Sisters is that three sisters lived in the Jamison Valley as members of the Katoomba tribe. They fell in love with three men from a neighbouring tribe , but marriage was forbidden by tribal law. The brothers were not happy to accept this law and so decided to use force to capture the three sisters. A major tribal battle ensued, and the sisters were turned to stone by an elder to protect them, but he was killed in the fighting and no one else could turn them back. This legend is claimed to be an Indigenous Australian Dreamtime legend.
However, Dr Martin Thomas, in his work "The artificial horizon: imagining the Blue Mountains", clearly shows that the "aboriginal" legend is a fabrication created by a non-Aboriginal Katoomba local, Mel Ward, presumably to add interest to a local landmark. The story originated in the late 1920s or early 1930s and is unknown prior to that date.
