JeremyC,

Yes, the age of the Canyon is stated on the website and the NPS office and in many books. The NPS or others cannot just delete that information from the website or amend it in books because it is science-based, peer reviewed material that can only be modified by contrary science-based evidence that passes peer review.

Please click on the other links within the original PEER link I provided it the initial post to this thread. The PEER letter is there and here are some excerpts for the letter:

{Quote}

"In the view of PEER, the practices at Grand Canyon NP with respect to the book Grand Canyon: A Different View and creationism are clearly at variance with the statutory and policy mandates underpinning your agency. We would request that you review this case and –

        1. Remove the book from sale at park bookstores and museums;

        2. Provide training to the interpretive staff at Grand Canyon NP regarding how to answer questions from the public concerning the geologic age of the Canyon and related matters; and

        3. Approve an updated version of the long-stalled pamphlet "National Park Service Geologic Interpretive Programs: Distinguishing Science from Religion" for distribution to agency interpretive staff.

Continued delay by NPS in forthrightly addressing this issue only undermines the credibility of your agency in its policies and pronouncements with respect to its educational mission and dedication to promoting excellence in science." {End Quote}
