Once Mike C discovers this post, you'll get his famous "No TP" lecture. He seems to feel quite strongly on this issue. Personally, I don't like to see or smell rocks and pinecones lying around with human waste on them. Nor do I like the idea of using green vegetation, especially in sensitive alpine areas.
I am female and, like most women who've had several children, have hemorrhoids. Therefore things like rocks, pine needles, etc. don't work for me and have the potential to cause injury and infection. I have to use nice soft TP plus wet wipes. If the ground is wet, the TP is buried the cathole with some water poured over it to help it disintegrate. The wet wipes are packed out. If the weather and ground are dry, both are packed out, because the TP won't disintegrate in dry conditions. Being a "Freezer Bag Cooking" fan, I use the used plastic freezer bags for this purpose. Multiple use--at both ends!
