The Indus Gorge withNanga Parbat, the world's ninth-highest mountain, rising to the south
TheIndus Gorge is agorge formed by theIndus River as it skirts theNanga Parbat massif, the western anchor of theGreater Himalayas, before itdebouches into the plains ofPunjab in Pakistan. The gorge is 4,500–5,200 m (14,800–17,100 ft) deep near the Nanga Parbat. The massive amounts oferosion due to the Indus River following the capture and rerouting through that area is thought to bring middle and lower crustal rocks to the surface.[1] Gilgit is the westernmost tributary of the Indus River.
