The lake near the Valley of Flowers at the height of 4329 m discovered by Sikh Havildar Sohan Singh in 1930, was identified with the one referred to by Guru Govind Singh - the tenth Guru of the sikh faith. Lying in heavenly environs, the place is revered both by Hindus and Sikhs, as well as for people from other faiths it is an important pilgrimage. Encircled by seven snow clad peaks and their associated glaciers, it reflects it surroundings enchantingly on its crystal clear serene waters. The glaciers from Hathi Parvat & Sapt Rishi Peaks feed the lake and small stream called Himganga flows out to this lake.
