The Hindu Kush range has numerous high snow-capped peaks, with the highest point in the Hindu Kush being Tirich Mir or Terichmir at 7,708 metres (25,289 ft) in the Chitral District of Khyber Pakhtunkhwa, Pakistan. To the north, near its northeastern end, the Hindu Kush buttresses the Pamir Mountains near the point where the borders of China, Pakistan and Afghanistan meet, after which it runs southwest through Pakistan and into Afghanistan near their border. The eastern end of the Hindu Kush in the north merges with the Karakoram Range. Towards its southern end, it connects with the Spin Ghar Range near the Kabul River.
Geologically, the range is rooted in the formation of a subcontinent from a region of Gondwana that drifted away from East Africa about 160 million years ago, around the Middle Jurassic period. The Indian subcontinent, Australia and islands of the Indian Ocean rifted further, drifting northeastwards, with the Indian subcontinent colliding with the Eurasian plate nearly 55 million years ago, towards the end of Palaeocene. This collision created the Himalayas, including the Hindu Kush.
The Hindu Kush range remains geologically active and is still rising. It is prone to earthquakes.
