"The first petroglyphic studies in this part of the Himalaya were mainly made by Hermann France. To add also those of Karl Jettmar of the rocks situated close to Pakistan. To note is that one of the main affluent of the legendary river, flows in this area. In the north south part of the Hunza river, the Karokoram Hwy was completed in 1982. Many trucks, beautifully decorated, now replace the caravans, as well as the army, that ever since antiquity had no other choice but to use this natural passage between Central Asia and the Indian continent or go over the high passes of the Himalaya".
