Jobe,
Just to clarify, I said "from what I've heard", meaning that it was second-hand information. I've had no dealings or discussions with the department myself. If they don't have an issue with nudity at DCHS, that's great, but it still wouldn't hurt to ask them for help with the littering. If they say no, or just don't do anything, well, at least they were asked.
As for jurisdiction inside a NF (someone else mentioned that), it is in fact within the jurisdiction of a county or state law enforcement official to enforce local laws within the boundaries of federal land, even lacking such a law in federal form. That's any federal land, anywhere in the U.S. Doesn't mean that they have to, or will, only that they can. Don't take my word for it, ask the USFS or NPS.
Jobe, I do remember meeting you a few months ago, I'm just not good with names. Not interested in your (or anybody else's) girl...got my own loving wife back home. You are very right about the "where are you from?", due to my accent...I get that all over the place!
