That is Among the World’s Longest Continuous Glacier Systems.
Snow Lake, or Lukpe La, is a high-altitude glacial basin in the Karakoram mountain range in the Northern Areas of Pakistan. It is not a lake.
Snow Lake is located 16,000 feet (4,877 m) above sea level, and is approximately 10 miles (16 km) wide. The basin lies at the head of the Biafo and Hispar glaciers, which spread down from the Hispar Pass in opposite directions, forming a 61 mile (100 km) river of ice that is among the world’s longest continuous glacier systems outside of the polar regions.
