The latest in a disturbing trend

I first learned about this from friend Mark H. (a former NPS Ranger, geologist) and now have read this post, The Grand Canyon is how old? at good old Pharyngula:

At this point, it's safe to say the National Park Service is stonewalling. There is a book called The Grand Canyon: A Different View, written from a young earth creationist perspective, which the NPS has approved for sale in its bookstores. It is a truly appalling piece of crap …

As Mark says: "When interpreters, scientists, and teachers can no longer speak scientifically verifiable truth without fear of reprisal, we are in serious trouble indeed."
