The sight of the beautiful circular glacial lake in the covering of snow all round it with its blue color does look beautiful to the eyes and is definitely photogenic, but what gives the lake its real worth is the name which it has got for itself - The Skeletal Lake. There are lots of other lakes in the Himalayas much beautiful than the Roopkund, but this lake is special. The mystery surrounding the lake and lots of scattered human bones which are too big for the current generation of Indians is what makes it one of the most sought after trek in the Himalayas. It took the World by its imaginations and lots of theories are available on the cause of the mass death. Recently, the theory of a pilgrimage hit by a massive hail storm causing the tragic death is more believable as per a research study.
