In Pakistan’s eastern Karakoram, Baltoro Glacier is one of the world’s largest valley glaciers. Though difficult to access, it is one of the most highly trafficked regions in Pakistan because of mountaineering destinations like K2, Broad Peak, and the Gasherbrum peaks at its head. The area is not only known for its stunning scenery, but as a life source–a large portion northern Pakistan’s population depends on meltwater from the Karakoram glaciers.
