Study contends Grand Canyon as old as dinosaur era

Grand CanyonThe awe-inspiring Grand Canyon was probably carved about 70 million years ago, much earlier than thought, a provocative new study suggests - so early that dinosaurs might have roamed near this natural wonder.

Using a new dating tool, a team of scientists came up with a different age for the gorge's western section, challenging conventional wisdom that much of the canyon was scoured by the mighty Colorado River in the last 5 million to 6 million years.

Not everyone is convinced with the latest viewpoint published online Thursday in the journal Science. Critics contend the study ignores a mountain of evidence pointing to a geologically young landscape and they have doubts about the technique used to date it.

The notion that the Grand Canyon existed during the dinosaur era is "ludicrous," said geologist Karl Karlstrom of the University of New Mexico in Albuquerque.

How the Grand Canyon became grand - with its vertical cliffs and flat plateaus - has been debated since John Wesley Powell navigated the whitewater rapids and scouted the sheer walls during his famous 1869 expedition.
