China’s Rainbow Rock Formations
In Gansu province China is one of the world’s natural wonders called the Zhangye Danxia Landform. There is a very similar formation about forty miles north of Las Vegas called Red Rock Canyon. Scientists believe that the rocks are the result of millions of years of movement of the earth’s crust, water fissures, erosion and oxidization caused by desert heat conditions. This has become a huge tourist destination in China with walkways and observation posts built for viewing.
