THE KARAKORAM HIGHWAY

The Karakoram Highway, or KKH, is the greatest wonder of modern Pakistan and one of the most spectacular roads in the world. Connecting Pakistan to China, it twists through three great mountain ranges - the Himalaya, Karakoram and Pamir - following one of the ancient silk routes along the valleys of the Indus, Gilgit and Hunza rivers to the Chinese border at the Khunjerab Pass. It then crosses the high Central Asian plateau before winding down through the Pamirs to Kashgar, at the western edge of the Taklamakan Desert. By this route, Chinese silks, ceramics, lacquer-work, bronze, iron, furs and spices travelled West, while the wool, linen, ivory, gold, silver, precious and semi-precious stones, asbestos and glass of South Asia and the West travelled East. 
For much of its 1,284 kms (905 miles), the Karakoram Highway is overshadowed by towering, barren mountains, a high altitude desert enjoying less than 100 millimeters (four inches) of rain a year. In many of the gorges through which it passes, it rides a shelf cut into a sheer cliff face as high as 500 meters (1,600 feet) above the river. The KKH has opened up remote villages where little has changed in hundreds of years, where farmers irrigate tiny terraces to grow small patches of wheat, barely or maize that stand out like emeralds against the grey, stony mountains. The highway is an incredible feat of engineering and an enduring monuments to the 810 Pakistanis and 82 Chinese who died forcing it through what is probably the world's most difficult and unstable terrain. (The unofficial death toll is somewhat higher, coming to nearly one life for each kilometer of road).

The Karakoram and the Himalaya, the newest mountain ranges in the world, began to form some 5 million years ago when the Indian sub-continent drifted northwards and rammed into the Asian land mass. By this time the dinosaurs were already extinct. India is still trundling northwards at the geologically reckless rate of five centimeters (two inches) a year, and the mountains are still growing by about seven millimeters (1/4 of an inch), annually. the KKH runs through the middle of this collision belt, where there is an earth tremor, on average, every three minutes.

Karakoram is Turkish for 'crumbling rock', an apt description for the giant, grey, snow-capped slag heaps that tower above the gorges cut between them. 

The Indus River flows northwest, dividing the Himalaya from the Karakoram, before being knocked south by the Hindu Kush. the KKH hugs the banks of the Indus for 310 kilometres of its climb north, winding around the foot of Nanga Parbat, the ninth highest mountain in the world and the western anchor of the Himalaya. The highway then leaves the Indus for the Gilgit, Hunza and Khunjerab rivers to take on the Karakoram Range, which boat 12 of the 30 highest mountains in the world. By the time the road reaches the 4,733 mere (15,528 foot). Khunjerab Pass, it has earned the name of the highest metalled border crossing in the world.
