Masherbrum Peak 7821-M (also known as K1) is the 22nd highest mountain in the world and the 11th highest in Pakistan.
It is the highest peak of the Masherbrum range, a subrange of the Karakorum Mountains. It is a large and striking peak, which is somewhat overshadowed by the nearby 8000m peaks of the main range of the Karakorum which includes four of the fourteen Eight-thousanders, namely K2, Gasherbrum I, Broad Peak and Gasherbrum II. The meaning of the name “Masherbrum” is not entirely clear. It may come from mashadar (muzzle-loading gun) plus brum (mountain), from the resemblance of the double summit to an old muzzle-loader. It may also come from masha (queen or lady), giving “queen of peaks.” Other meanings have also been suggested.
Location
The Masherbrum range lies to the south of the Baltoro glacier and the main range of the Karakorum lies to the north of the Baltoro. The main range is the continental divide of Asia. Rivers to the south flow into the Arabian Sea. Rivers to the north flow to the Yellow Sea.
The Baltoro Glacier is the route most commonly used to access the 8000m peaks of the Karakorum, and many trekkers also travel on the Baltoro. Masherbrum also lies at the north end of the Hushe valley, which serves as the southern approach to the peak.
History
In 1856, Thomas Montgomery, a British Royal Engineers lieutenant, noticed a tall mountain in the Karakorams and called it K1 (denoting peak 1 of the Karakorum). To the local people of the area, it is known as Masherbrum.
Masherbrum was reconnoitered in 1911 by the intrepid Dr. William H. Workman and his wife Mrs. Fanny Bullock Workman. It was first attempted in 1938 from the south; the attempt failed just short of the summit.
After two more failed expeditions, in 1955 and 1957, Masherbrum was first climbed in 1960 by George Irving Bell and Willi Unsoeld, part of an American-Pakistani expedition led by Nick Clinch. They succeeded in climbing the southeast face route that had stymied the earlier parties.
The Himalayan Index lists three additional ascents and six additional failed attempts on Masherbrum. The ascents include two by additional routes, the NW Face and the NW Ridge/N Face
