Masherbrum (also known as K1) is located in the Ghanche District, Gilgit Baltistan of Pakistan. At 7,821 metres (25,659 ft) 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 its name.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.
