Lake Puma Yumco

Puma Yumco lies high on the southern Tibetan Plateau, beneath snow-covered mountains. Its name means Blue Jewel Lake, and its waters freeze in winter. The lake contains islands with grass on which herders graze sheep, driving their animals across the ice when it is thick enough. Fish inhabit the water, but are regarded as sacred by many Tibetans. The lake and its shores form a striking feature of the cold highland landscape.
