The 3,544ft Southern Sky Column in Zhangjiajie National Forest Park
"Its soaring steeple of rock topped by a small oasis of trees looks straight out of the 3D blockbuster Avatar.
But this is no special effects illusion, it's a real-life tower of quartz-sandstone deep in the rugged mountain terrain of southern Hunan in China.
The 3,544ft Southern Sky Column is one of 3,000 in the Zhangjiajie National Forest Park and became the inspiration for the magical 'floating peaks' in James Cameron's film after a Hollywood photographer spent time shooting there in 2008."
