Which Pakistan glacier is 63 km long and lies near K2 in the Karakoram?

Pakistan’s 63-kilometer-long glacier near K2 is the Baltoro Glacier. It lies in the Karakoram range of Gilgit-Baltistan and is surrounded by some of the world’s highest mountains, including K2, the second-highest peak on Earth.

The Baltoro is a major mountain glacier and a famous approach route for expeditions to K2 and the Concordia trekking area. At Concordia, around 4,600 meters above sea level, the Baltoro meets the Godwin-Austen Glacier, which descends from the K2 region. The glacier’s meltwater helps form the Braldo River, which eventually joins the Shigar and Indus river systems.

The nearby alternatives are also important Karakoram glaciers, which can make this question tricky. The Biafo Glacier is about 67 kilometers long, Hispar Glacier is another major glacier in the region, and Rimo Glacier lies farther east. Baltoro is specifically identified by its 63-kilometer length and its famous position near K2.
