Exactly 310 million years old?
That’s what ended the dinosaurs. She flashed them.
Are they sure those aren’t ATV tire treads?
Or maybe a few hundred million fewer years than 310,000,000. It might also be the mud tire of a Jeep Wrangler.
310 million, 2 days, 4 hours, and 12 seconds.
Take this!...
Exactly, and not a day older or younger!!! snark, snark...
A big hole and a big ho........................
Mebbe he was sidestepping around those perfectly straight crossing lines so as not to mess them up?
Interactive geologic map of the Grand Canyon area:
http://rclark.github.io/grand-canyon-geology/
AZGS wunderkind Ryan Clark has built a demonstration interactive geologic map of the Grand Canyon region, using the geologic maps prepared by George Billingsley of the USGS.
Run your cursor over the map and the geologic unit name and description appear in the legend at the lower left. Although the maps were published at 1:100,000 scale, the original mapping was done at 1:24,000
That is so amazing. The world is truly a glorious place.
From the peculiar gate, it would appear to be the earliest discovery of Hillary Rodham’s decedents...
As predicted - thank you !
Thanks ETL. And yes, I do make my own fun, sometimes. :^)
If the Grand Canyon is, say, forty million years old and Ice Ages occur, say, every forty thousand years, then the Grand Canyon must have been covered with ice over a thousand times in its history. Odd that the Colorado River can leave its mark, but being covered by an ice pack a mile thick a thousand times -- for centuries at a time -- does not. [JoeSchem]
I am one of those weirdos who think the Grand Canyon was carved down in a much shorter time, and not so long ago.
From the air it looks so much like drainage from the huge ocean that was icebound in Canada and the Plains.
So, foot prints in mud at any level in the grand canyon is suspect in my mind.
Just my opinion. And I am a pretty hardcore traditional geologist guy from way back when Fossil Fred was teaching on the hill.
“Some 310 million years ago, a reptile-like creature with an unusual gait roamed the sandy expanses of the Grand Canyon”
The first dinosaurs are thought to have appeared somewhere around 225-235 million years ago.
