Tang-e Gharu
Tang-e Gharu, also known as Tang-e Gharo (Pashto: تنگ غارو), is a gorge and a mountain pass in the Hindu Kush mountain range of Kabul Province, Afghanistan.[1] The Kabul River passes through the gorge flowing eastward.[2] The Kabul–Jalalabad Road runs through the gorge, parallel to the river.[3] Construction on the road began in the 1940s, and was completed in the 1960s.[3][4] Both the pass and the road are considered of major strategic importance, as they provide a connection to Pakistan and Russia.[5][6] Due to heavy usage during most recent conflicts in Afghanistan, as well as frequent traffic accidents, the pass and the surrounding area are heavily damaged and periodically closed off.[3][7]
Geology
The cliffs of Tang-e Gharu gorge are a blue-grey limestone, which was formed some 250 million years ago. The gorge itself is only about 2 million years old, however, and was formed as a combination of water erosion from the river and the collapse of an underground river channel.[2]
