River Thalos

The second of the six rushing rivers that rushed down from the Blue Mountains to meet the great River Gelion. The Thalos, whose name comes from the Elvish for 'torrent', is important in the history of Men. It was in the high valley of its upper course that the first Bëor and his followers, the first Men to cross the mountains, made their camp, and where they were discovered by Finrod Felagund.
