Interesting post... this comes from a press release from this group PEER, which also was run by skeptic.com (which is banned on FR for reasons I know not); but some of skeptic's readers were, well, skeptical.
The National Park Service staff are outraged at the suggestion that park staff are expected to teach young-earth creationism. It's complete hooey, as the staff of "skeptic" discovered when they investigated (after, mind you, running the press release).
Here is what the NPS actually says about the geological history of the Grand Canyon (scroll down):

So as you see, the article is bullsh..... er, inaccurate. The editor of "skeptic.com" (a website) gamely ate crow over this issue and now believes that the PEER press release was fabricated. The MSM outlet that ran the story in this thread probably won't.
New media on one hand, old media on the other. Think of it as evolution in action.
