Photo of the Day: Prayer Flags at Nam Tso Lake

The five colors of traditional Tibetan prayer flags represent the elements of fire, water, earth, wind and sky. Namtso lake in the background is the highest salt water lake in the world at an elevation of 15,479 ft (4,718m). It is also one of the most sacred bodies of water in Tibetan Buddhism and many pilgrims come to Namtso to circumnavigate its shoreline, which is no easy task as the lake is approximately 70km long and 30km wide.
