Here's an article of absurdity. Religious people are the dumbest fucking group of people I've ever encountered...and Fundamentalist religious groups are some of the most dellusional masses of human waste on the planet.
Of course, thats a bit of an exaggeration, but not telling people the stratigraphic age of the grand canyon in order to avoid offending religious zealots should be grounds for termination at the park service.
As an educated geologist and working professional, I'm offended that my national park service is bowing to a group of assholes and ruining the true dynamic history of one of the coolest places in the United States.
my favorite quote:
"As one park geologist said, this is equivalent of Yellowstone National Park selling a book entitled Geysers of Old Faithful: Nostrils of Satan"
