Strange Natural Wonders of the World

Mother Nature is full of surprises. From a landscape of bubbling, gurgling mud volcanoes to swirling, blue walls hidden in a cave, the world is dotted with spectacular, natural oddities that may seem too strange to be real. But they are, indeed, real.

Many of the world's most amazing sights can be found in the vastness of China. One of its natural treasures is the Zhangjiajie National Forest Park in Hunan Province. With its deep canyons, majestic waterfalls, and sandstone-quartz pillars towering over 650 feet high, the site looks straight out of 3D science-fiction film. So it's no surprise that one of the park's rock formations the 3,544 ft Southern Sky Column inspired the fictional world of "Pandora" in James Cameron's blockbuster film Avatar.
