Grand Canyon far older than previous estimate

"A new dating technique has put the age of the Grand Canyon at 17 million years old, three times older than earlier estimates, according to a report in the latest edition of the journal Science.

The latest in uranium-lead isotope dating allowed researchers to study the canyon's "cave clouds", the mamillary coatings of carbon deposits that gather on the canyon walls at or near the water table, the journal said in its edition released Thursday.

"The canyon is older than we think," said Victor Polyak, a geologist at the University of New Mexico and principal author of the paper."

Interesting. When I listened to a ranger describe how and when the canyon was formed they seemed so sure. That means the whole plateau lifted that long ago which throws the entire geological picture of the area into disarray.

That stinking Bush.

That stinking Bush.

All that man-made pollution millions of years ago caused global warming and melting of the polar ice caps. Fortunately, the resulting flooding was limited to the Colorado river which etched and gouged the Grand Canyon in that one limited area.

I was staying awake nights worrying about the age of the Grand Canyon. I, for one am certain that this new information will mean a great deal in my life.
