Masherbrum Masherbrum Masherbrum (; formerly known as K1) is located in the Ghanche District, Gilgit Baltistan of Pakistan. At it is the 22nd highest mountain in the world and the 9th highest in Pakistan. It was the first mapped peak in the Karakoram mountain range, hence the designation "K1". Masherbrum is the highest peak of the Masherbrum Mountains, a subrange of the Karakoram range. It is a large and striking peak, which is somewhat overshadowed by the nearby peaks of the main range of the Karakoram which includes four of the fourteen Eight-thousanders, namely K2, Gasherbrum I, Broad Peak and Gasherbrum
K2 unable to keep pace. The mountain was first surveyed by a European survey team in 1856. Team member Thomas Montgomerie designated the mountain "K2" for being the second peak of the Karakoram range. The other peaks were originally named K1, K3, K4, and K5, but were eventually renamed Masherbrum, Gasherbrum IV, Gasherbrum II, and Gasherbrum I, respectively. In 1892, Martin Conway led a British expedition that reached "Concordia" on the Baltoro Glacier. The first serious attempt to climb K2 was undertaken in 1902 by Oscar Eckenstein, Aleister Crowley, Jules Jacot-Guillarmod, Heinrich Pfannl, Victor Wessely, and Guy Knowles via the Northeast
