The Northern Areas has five of the world's seventeen highest peaks along with highest range of mountains the Karakoram and Himalayas. It also has such extensive glaciers that it has sometimes been called the "Third Pole". The international border-line has been a matter of pivotal dispute between Pakistan and India ever since 1947, and the Siachen Glacier in northern Kashmir has been an important arena for fighting between the two sides since 1984, although far more soldiers have died of exposure to the cold than from any skirmishes in the conflict between their National Armies facing each other.
