Agree with everything. Only thing I mentioned otherwise was that this Glacier is different & Samudra Tapu is different. Samudra Tapu is somewhat towards North, this one towards west.There was another thread of a gentleman who had stayed at the Chandratal camps for 3 days and explored the surroundings. It had even more details. Can't seem to find it now. But for all I know, this water body is the leftover of a retracted glacier (Samudri Tapu?) which essentially forms into an independent glacial lake in due course of time.
