Also known as Mount Godwin-Austen, K2 is the second highest mountain in the world. The mountain is 28,251 feet high and it is thought to be more difficult to climb than Mount Everest. When climbers arrive at the base, they are amazed by the steep rock face of the mountain and awed by the weather. The mountain is located on the border of China and Pakistan, which is in the Karakoram part of the Himalayan mountain range. Most climbers attempt to reach the top of K2 from Pakistan, but no one has ever tried to climb the mountain in the winter. Two people from an Italian expedition team were the first to reach the top of K2: Lino Lacedelli and Achille Compagnoni. They reached the summit, or the top of the mountain, in July, 1954. Since then, almost 300 people have managed to reach the top of the mountain.
