Or at least that's what the advocacy group, Public Employees for Environmental Responsibility claim. To wit:
Grand Canyon National Park is not permitted to give an official estimate of the geologic age of its principal feature, due to pressure from Bush administration appointees. Despite promising a prompt review of its approval for a book claiming the Grand Canyon was created by Noah's flood rather than by geologic forces, more than three years later no review has ever been done and the book remains on sale at the park, according to documents released today by Public Employees for Environmental Responsibility (PEER).
The creationist book in question is Grand Canyon: A Different View. My favorite line about the creationist book that is still on sale at the park bookstores is:
“As one park geologist said, this is equivalent of Yellowstone National Park selling a book entitled Geysers of Old Faithful: Nostrils of Satan."
