The final part of this excursion was to take the short drive from Scenic World to Echo Point a lookout about 2 kilometres (1.2 mi) south of Katoomba. The lookout offers a view to Three Sisters, Mount Solitary and the rock formation known as the Ruined Castle.
The Three Sisters are an unusual rock formation on the north escarpment towering above the Jamison Valley which you can see behind in the photo. Their names are Meehni (922 m), Wimlah (918 m), and Gunnedoo (906m).
The Three Sisters were formed by land erosion around 200 million years ago during the Triassic period when the sandstone of the Blue Mountains was eroded over time by wind, rain and rivers, causing the cliffs surrounding the Valley to be slowly broken up.
The commonly told legend of the Three Sisters, according to Wikipedia, is that three sisters, Wimalah, Meeni, and Gunedoo, lived in the Jamison Valley as members of the Katoomba tribe. They fell in love with three men from the neighbouring Nepean tribe, but marriage was forbidden by tribal law. The brothers were not happy to accept this law and so decided 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.
The third photo is towards the rock feature named the Ruined Castle.
