Is this the oldest photograph of Triveni from Peshoke View Point (1870)

Every one is quite familiar with this iconic photograph of Triveni taken from Peshoke View Point. The famed triveni is the place where the two great rivers of Sikkim - the Teesta and Rangeet meets and unites to form a new river that finally meets Bay of Bengal in the Sundarban Deltas. Teesta originates from Tso Lhamo Lake also called Cholamu in north Sikkim at an altitude of 17,500 ft (i.e. 5,330m). While Rangeet originates from a glacier of Mount Kabru at the lower Kanchenjunga region. 

But the interesting fact is that i bet the photograph above is one of the first taken of this popular side. The picture is taken by Robert Philips and the date of circulation in 1870.
