The Great Divide...

                                        ... of the South and the North Rims of the Grand Canyon.

 

"The debate over the age of the Grand Canyon has raged for over 140 years: It's old! It's young! It's really, really old! It's not as old as you think! But now a paper in Nature Geoscience offers a possible compromise: Yes, the Colorado River has been carving the Grand Canyon for only 6 million years, but it is flowing through canyons that date back about 70 million years.

 

Call it Mother Nature's recycling effort.

 

Back when dinosaurs were wrapping up their time on Earth, rivers were carving a path through what is now Arizona. Time passed, the rivers dried up, and the canyons stood, dry and empty, for tens of millions of years. Not too far away, another canyon was carved, about 20 million years ago. Then, just 6 million years ago, snowmelt from the Rocky Mountains began seeking a path to the ocean, and the rushing water took advantage of these canyons as it headed west to the Pacific, ultimately becoming the Colorado River."

I can't add anything to the age debate but I can marvel at the view. Is that traces of snow on the left?
Elizabeth Croston Buckalew: It's all we can do... Yes it is!

Although this place is carved out of the land, the sun also does a bit of carving with light.
