In 1984, an Indian army expedition under Colonel Prem Chand took hold of this peak, from the side of Siachen glacier by traversing from the west.

K12 was used for training for the Mount Everest expedition of the Indian Army in 1985.

It was first attempted in 1960, after a reconnaissance visit by famed explorer Eric Shipton in 1957.
