How Old is the Grand Canyon?

How unsettling to find this excellent essay from (the really, rather remarkable) Sam Harris, and then to immediately find this disturbing piece on what Grand Canyon National Park employees are not permitted to discuss with park visitors.

    Yah, that NPS stance is absolutely absurd. I’d like to get down there, take a guided tour and find out what’s really going on from the rangers themselves.

    Spoiler … according to the internet, and specifically Wikipedia, the Grand Canyon may be less than 5 or 6 million years old. (Caveats: the article implies that dating the age of the Grand Canyon is a challenging geologic exercise; and, we all know that Wikipedia is unreliable, so stick with the other dates that are out there if needing something official. Better yet, make one up. Geology doesn’t really know anyway.)
