Due to pressure from Bush appointees, park rangers at the Grand Canyon are not allowed to tell visitors the true age of the canyon, according to this press release from the Public Employees for Environmental Responsibility (PEER). Unfortunately, this little piece of threatiness seems to have been made up from thin air.

A former national park ranger has done some digging, and quotes from the Grand Canyon National Park reply:

If asked the age of the Grand Canyon, our rangers use the following answer. The principal consensus among geologists is that the Colorado River basin has developed in the past 40 million years and that the Grand Canyon itself is probably less than five to six million years old. The result of all this erosion is one of the most complete geologic columns on the planet. The major geologic exposures in Grand Canyon range in age from the 2 billion year old Vishnu Schist at the bottom of the Inner Gorge to the 230 million year old Kaibab Limestone on the Rim.
