‘We have now come to the River Hoarwell, that the Elves call Mitheithel. It flows down out of the Ettenmoors, the troll-fells north of Rivendell, and joins the Loudwater away in the South. Some call it the Greyflood after that. It is a great water before it finds the Sea. There is no way over it below its sources in the Ettenmoors, except by the Last Bridge on which the Road crosses.’
