These pictures of great sandstone walls were not taken at the Antelope Canyon in Arizona, but rather in Keziliya Mountain, about 70 km north of Kuqa in Xinjiang Uygur Autonomous Region in China. The Keziliya Grand Canyon, also called the Tianshan Grand Canyon being located at the south foot of the Tianshan Mountain, is about 5.5 km long from east to west and was formed due to erosion by flash flooding over thousands of years, just like its bigger brother in Arizona. The canyon is characterized by oddly-shaped rocks, pinnacles, rugged cliffs and deep ravines. These have been given various names such as “Skyworth Valley”, “Sacred Snake Valley”, “Skyscraper Cave Valley”, “Rock of tenterhook”, “Swan Peak” and “Lover’s Peak”, to name a few.
