Bhutan - Haa valley - Prayer flags hanging from pine trees and the Haa Chhu river in Yangthang villa

Prayer flags hanging from pine trees and the Haa Chhu river in Yangthang village, Haa Valley, Western Bhutan. Prayer flags are ubiquitous in Bhutan and come in five colours - blue, green, red, yellow and white - symbolising the elements of water, wood, fire, earth and iron. The prayer for the flag is carved into wooden blocks and then printed on the cloth in repeating patterns. (Photo by In Pictures Ltd./Corbis via Getty Images)
