How come Rivendell was never discovered by Sauron?

[Morgoth the Great]

Sauron knew, of course he did. and he was actually moving down towards it. He was coming from the north, from Angmar with his Nazgul and some orcs. This was long before the real war of the ring began, but Glorfindel fought them back(not only him, but he commanded the host) Fornost was taken by the Nazgul in 1974. The forces then went south, but were beaten back by Cirdan's and Glorfindel's men. Sauron then abandoned attacking Rivendell as an original objective, and instead decided to take out the much weaker targer: Gondor. I believe it is Gandalf who states that Rivendell is safe until all else falls. just my thoughts on the matter [img]smilies/smile.gif[/img]
