Falling question

[DizzyKungFu]

How do you decide when a character that fall whether they are prone or not? I can't find a rule that states this, one way or the other, but I have a hard time believing a PC that falls 200 ft. (and takes 20d6 damage) isn't prone after this.

I assume that a falling character is automatically prone, unless he succeeds at a Tumble check (or a Dex check).
