The lower caves are called "Satt Ghariyoon" (Seven Caves).[2][3].Nearby the upper caves, the top of the hill is surrounded by very ancient compound wall which is constructed with stones. The remains of ancient settlement and very old potsherds have been explored. The discovered earthenware or ceramic material refers to earlier Indus Valley Civilisation while the period of caves has been considered as the Stone Age.[4].In the vicinity of Kai Valley, close to Kai Caves, the other sites of Bulo-Ji-Buthi, Nuko-Buthi, Kai-Buthi and Naig have been discovered belonging to prehistoric and Chalcolithic periods.[5] Dr. Louis Flam had visited the Kai Caves with native archaeologist Taj Sehrai in 1976.[6]
