The Three Sisters is a well-known rock formation in the Greater Blue Mountains of New South Wales, Australia, located on the north slope of the Jamison Valley. The Sisters’ names are Meehni at 922 m (3,024 ft), Wimlah at 918 m (3,011 ft), and Gunnedoo at 906 m (2,972 ft). They were formed around 200 million years ago, when volcanoes erupted through the coal, sandstone, and shale in the area. A UNESCO World Heritage site since 2000, the Greater Blue Mountains are home to over 400 kinds of rare animals, as well as unique plants.
