Kashafrud — Wikipedia

Kashafrud Basin (Persian: کشف‌رود) is an archaeological site in Iran, known for the Lower Palaeolithic artifacts collected there; these are the oldest-known evidence for human occupation of Iran. Kashafrud includes a cluster of sites which are located 35 km to 85 km southeast of Mashhad, near the Kashafrud River. The French geologist Claude Thibault, in collaboration with the Iranian geologist Ali Ariai, conducted surveys in the Kashfrud basin east of Mashhad in 1974–75, during which 80 stone artifacts were collected from seven open areas.
