Because of the high altitude and strong winds, Bird's can't fly over the Pangong Lake. Pangong lake is situated near Leh-Ladakh in the Himalayas Range in India, approximately at the height of 4350 meters. This endorheic lake is 12 kilometres long and extends from India to Tibet, with two-thirds of it lying in the latter. Owing to its altitude, the Pangong Lake temperature ranges from -5C to 10C as a result of which it freezes completely during winters in spite of its salinity. A unique feature of the lake is that it does not remain blue throughout the year or even the day, rather it changes colours from azure to light blue to green and grey too!
