Ford of Carrock
Ford of Carrock is, according to Glóin's words in Rivendell, a ford that the Beornings kept open (even if their tolls were high). But in The Hobbit (Chapter VII) the ford is clearly told only to reach from the eastern bank of Anduin to the Carrock. It was made of "huge flat stones" that "led to the grass-land beyond the stream". But afterwards Gandalf told to the dwarves and Bilbom that "it is easy enough, as you remember, to get from this [eastern] bank to the Carrock by ford, but on the other side is a cliff standing up from a swirling channel." Gandalf could not cross the river there when he was following the track of Beorn.
Robert Foster (The Complete Guide to Middle-earth s.v. Ford of Carrock) supposes that Glóin's reference should be to the Old Ford.
