This is not Gosaikunda lake. Well, the cut off one on the left is, but it's not the focus of the picture and that's misleading. This lake is called Saraswatikunda. [1] my trekking map would have been a better reference but I threw it out when I was finished with it.
Anyway, it's a nice picture, but the name is wrong.
