Sarn Athrad (Sindarin for 'Ford of Stones') was a stony ford on the river Gelion in the East Beleriand. It was located in the southern part of Thargelion and a little north of the river Ascar (Rathlóriel) of the land of Ossiriand. The Dwarf-Road that ran from the Dwarvish cities in the Blue Mountains (Ered Luin) all the way to Menegroth in Doriath, crossed the ford.
