But surely it would exist even if it was not grave in the literal sense? I mean, there would be still be a place where what was left of Arwen would exactly be, the bones etc wouldn't vanish anywhere. Maybe her remains were just covered by leaves and mould naturally when time passed and thus she was "buried" and she would have a "grave", that would probably be green when grass started to grow on it. That's how I see it, at least.
