The Blue Mountains
The aboriginal dream-time legend has it that three sisters: Meehni, Wimlah and Gunnedoo, lived in the Jamison valley. These ladies had fallen in love with 3 brothers from the Nepean tribe. It was forbade for them to marry. A witchdoctor from the Katoomba tribe took it upon himself and turn the 3 sisters into stone to protect them from harm. After the battle he intended to reverse the spell but he died.
The Blue Mountains was believed to be formed around one million years ago. Pressure from the east raised the area upwards in a monoclinal fold, reaching an elevation of around three thousand feet to the top. Rivers or any other type of running water helped create the form it is now.
