On July 31, 1954, Italian mountaineers Achille Compagnoni and Lino Lacedelli became the first people to reach the summit of K2, the world's second-highest mountain peak. K2 is part of the Karakoram mountain range between China and Pakistan, and rises 8,611 meters (28,251 feet) above sea level.

Even though K2 (Chhogori or Ketu in indigenous languages) has a lower elevation than Mount Everest, many mountaineers say it is steeper and much more difficult to climb. Nicknamed the “Savage Mountain,” K2 has never been successfully climbed in winter.
