The river that separates Ásgarðr from Jötunheimr, according to Gagnráðr in Vafþrúðnismál:

Ifing the stream is called
which earth divides between
the Jötuns and the Gods:
open shall it run
throughout all time.
On that stream no ice shall be.

The stream never freezes, so that the jötnar cannot cross it. There is no other reference to this particular river.
