Safed Koh (säfādˈ kō) [key], mountain range on the Pakistan-Afghanistan border, SE of Kabul; rises to 15,620 ft (4,761 m) at Mt. Sikaram. It parallels the Kabul River. A spur of the range is crossed by the Khyber Pass. The lower slopes are nearly barren; pine and deodar formerly grew on the main range, but devastation during the Afghan civil war reduced timber resources. The valleys support some agriculture.
