Grand Canyon Controversy! - Just how old is the Grand Canyon? While the conventional view is that the Colorado River carved the canyon about 6 million years ago, a new study provides evidence for the opposing view that the canyon is 10 times that old, 70 million years old -- old enough for the dinosaurs to have taken a look, even older than the Colorado River itself.

Graduate student Ajay Limaye visits 6th grade class at Hughes Middle School in Long Beach
