Wayne Ranney, Geologist, Guide and Author of Carving Grand Canyon: Evidence, Theories, and Mystery presented a 1 hour illustrated presentation on the latest theories related to the geological history of Grand Canyon. Wayne first became interested in earth history while working as a backcountry ranger in the park from 1975 to 1978. Wayne has taught geology at Yavapai and Coconino Community Colleges and Northern Arizona University and leads numerous hiking and rafting expeditions throughout the Southwest for the Grand Canyon Field Institute and the Museum of Northern Arizona.
Wayne is a great guy; to hike with him is a great pleasure. I had the opportunity to be part of North-South rim hike group of GCFI with him in 2002 and he gave us plenty of information on the canyon and geology aspects.
Agreed, I was able to attend a two day Grand Canyon seminar lead by Wayne five or six years ago. It was awesome, the guy is a great geology interpreter.
This is a very helpful presentation. Thanks for the information and insights.
Great lecture. I’m surprised there was no mention of uplift.
Interesting lecture, thank you. I have your book, Carving Grand Canyon, and highly recommend it. :)
Great presentation on the geomorphic history of the Grand Canyon!
Superlative Presentation and content !!! I must purchase these books. Thank you !
Great show full in interesting information
Enjoyed this lecture! 👍
the aftermath of mt. st that it does not take a long time to lay down layers and carve out a large canyon and that a large catastrophic flood can do it. lots of similar looks there.
I came here to see the new carving of this...
How did it form? Multiple floods is my first guess.
That’s actually my stepgrandpa
The dirt and the rocks are old, among the oldest on the planet. The canyons, the depth, and the sprawl, not so much. Maybe less than 3,000 years, for most of it. Maybe as little as 800 years, for for the Colorado River (before it was controlled by dams) to cut the final 1,500 feet.
Looks like it's been mined for *Ma
Wrong wrong wrong... The Colorado River did not carve the Grand Canyon... It's roughly 5000 years old, and it was carved out in a matter of weeks from Grand Lake.
2nd!
You should quit your job today
What qualification do you have to make such a suggestion? Have you ever attended a geology lesson? And I mean a real one at University, not the clown shows where paid liars are fantasizing about an invisible man in the sky with a rage problem who sends a lot of water from... whereever it magically came from and which somehow magically creates the Grand Canyon.
I am constantly amazed by the audacity of loudmouths like you who, despite being clueless and ignorant af, think they can lecture people who studied this stuff their whole life.
