The Elves call it Caradhras the Cruel and men call it Redhorn (see also the Redhorn pass they are trying to reach).

Apparently, the dwarvish name is Barazinbar.

ETA: way x-posty. Why am I distracted by work when trying to post on important Tolkien issues, I ask you?!!1

After Frodo finishes his book and passes it on to Sam, Sam adds to it, doesn't he?

I've abused more people for this paper, I swear.

Yes -- Sam finishes the book and it goes to his heirs.

What exactly does Sam add? In the movie, it seems like Frodo finishes the Lord of the Rings story, but I guess he couldn't actually write about anything that happened after he left.

I think that there is more stuff about his family -- and about Merry and Pippin and their families.

I think that one of Sam's daughters goes to Minas Tirith to be a Lady-in-Waiting to Queen Arwen, for example.

And I think that Elanor marries Pippin's son Faramir.

I'm planning to reread these after the RoTK EE comes out, I swear.

Thanks.

I think Sam keeps track of Merry and Pippin and himself, with accounts of King Elessar.

Also the stuff at the beginning of the book? The forward or prologue or whatever? "On hobbits" and "On pipeweed" -- that's from the Red Book of Westmarch.

I think that one of Sam's daughters goes to Minas Tirith to be a Lady-in-Waiting to Queen Arwen, for example.

Not Minas Tirith, but Annuminas, which was just north of the Shire, and was the old capitol of Arnor. King Elessar re-established the kingdom in the north and at times moved his court there for extended stays.

From Sam's family tree in RotK Appendix C:

Sam's oldest daughter Elanor married Fastred of Greenholm. "They removed to the Westmarch, a country then newly settled (being a gift of King Elessar) between the Far Downs and the Tower Hills. From them came the Fairbairns of the Towers, Wardens of Westmarch, who inherited the Red Book, and made several copies with various notes and later additions."

Sam's third daughter Goldilocks is the one who married Faramir Took, son of Pippin.
