After passing from the vicinity of the cities of Radkan and Chenaran in Razavi Khorasan Province and then passing north and east of the city of Mashhad, the Kashfrud joins the Harirud River at the frontier of Iran and Turkmenistan.

Kashafrud Basin
Kashafrud Basin 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. On the basis of their geological contexts, this collection is more than 800,000 years old. Thus, Kashfarud is one of the oldest human settlements in Iran.
