What national parks allow nudity?

I know that national parks theoretically have no national law governing public nudity, but I've seen some confusing information about this. One thing that got my attention today was that Deer Creek hot springs at San Bernardino NP specifically states on the website "Public nudity is not permitted within 1/4 mile of T-6 crossing" (a href="http://www.fs.fed.us/r5/sanbernardino/recreation/deepcreek/)" rel="nofollow"http://www.fs.fed.us/r5/sanbernardino/re…/a which I ume means it's allowed everywhere else. Are there any others that specifically state they allow it?
