At 63 kilometers (39 miles) in length, the Baltoro Glacier, located in the Gilgit-Baltistan region of Pakistan is one of the longest non-polar glaciers in the world. It’s by some 30 tributaries and has a surface area of 1291.39 square kilometers (about 500 square miles).

This part of Pakistan is home to some of the world’s highest mountains, and this glacier runs through part of the region’s Karakoram mountain range. It’s near a mountain known as K2, highest mountain in the region at 8,611 meters (28,251 feet). Three other nearby mountains within 20 kilometeres all top 8,000 meters as well.

Three of the world’s seven longest glaciers outside the polar regions are located in Gilgit-Baltistan– the Biafo Glacier, the Baltoro Glacier, and the Batura Glacier.

Bottom line: At 63 kilometers (39 miles) in length, Baltoro Glacier in Pakistan is one of the longest glaciers outside the polar regions.
