Kyrgyzstan’s southern neighbor Tajikistan is the country with highest average elevation in the world. Tajikistan is located on Pamir mountain range that connects The Himalayas with the Hindu Kush and the Tian Shan, forming what John Wood, a 19th century British explorer, called Roof of the World, translating local expression Bam-i-Duniah.
