Dramatic Canyons Reveal The Future of Florida

I've had a few ask about the impact crater Chicxulub and the formation of cenotes. The limestone which the cenotes formed in was deposited AFTER the impact. However, the impact most certainly would have fractured the older underlying limestone which could enhance the future development of cenotes in later younger limestone deposits. There is evidence that there are more cenotes along edge of the impact where massive fracturing and faulting occurred. It is important to note that there would be cenotes and other karst features without the impact. All limestone becomes fractured through time and also has bedding planes that allow for the fresh water to flow through and dissolve the rock. Bottom line; the impact created more fractures than normal which lead to the formation of more cenotes (much later) than without the impact.

A couple of viewers have informed me that I pronounced the Floridan aquifer wrong....I said it as "Floridian"...oops

It's always a good day when another Myron Cook video drops..

I was a geology major once upon a time before I was called to another life. Still love learning more, so I am happy to have your videos!

Sobering thoughts. As a Floridian for 51 years, I always thought Florida was just a big sand bar. He explains that the sporatic sink holes over our limestone strata (2500' deep) will expand over millions of years. Right now more coastal high-rise condos are experiencing foundation settlement causing costly damage to buildings. 13:06 He is suggesting parts of Florida will eventually collapse under water!

01:44 The way you describe the beauty of the canyon and its geological history is truly captivating! Your ability to connect the stunning landscape with deep time and natural processes is inspiring and makes me appreciate the world in a whole new way. Thank you for sharing this incredible insight!

Thinking about deep time in terms of geological features is such a humbling thing. My background is in astronomy and astrophysics, so ive mostly been humbled by the sheer size of the universe. With geology, I have another direction to be humbled in, but in this case its with time instead of space

I live here in Florida, and made a well at a ranch a while ago. At first we only dug about 30 feet down and the water we got out of it had an extremely high concentration of iron. If you filled a bucket with water and left it out for a few hours, it would turn completely red and opaque. It wasn't until we took the well deeper that we got clean water.
This was in the SW region.

Myron Cook is such a talented educator! He makes geology so easy to understand. These videos all seem like they could be on PBS

You have the best geology videos. Appreciate the time you spend on them

[gregjones]

You take me where I've been many times and make it new again. Thank you so much.

[rogueyun]

Thank you so much for sharing this! A masterclass not only in geology but in teaching in general! Thank you!

I love your perspective on time and how you break down the changes between deposition, erosion, etc all in the same location. I started me geology journey watching you and it’s become a real passion of mine. I picked up a roadside geology book for my state and have learned so much

Thanks for another wonderful teaching video. I would never have guessed the irregular positioned red rock in cliffs in your areas like that - what it looks like as founded so long ago compared to newer cases like Florida, and especially such visible ones as in Yucatan. I enjoy the things you teach so well, how to see what something looks like after such long and different lengths of form and change.

Your exposition of geologic time is fascinating; profoundly fascinating! Marvelous! Thanks!

[Taomantom]

You, sir, have the soul of a poet. Always informative and enticing. Thanks!!😎

[BrickNewton]

Im glad theres a new video. I've been binge watching the channel and running out of unwatched videos.
Keep up the outstanding work.

[vinnynorthwest]

Wow! That was so interesting! And your photography in Wyoming is incredible. Thank you Myron for another great video!

[willswift]

Appreciate you taking the time to go down to Tulum to shoot this video. The sacrifices you make in the name of teaching geology are commendable!

[herbrabe]

I am learning so much from your videos. I had no idea a person can tell so much from looking at rock. Keep up the good work

Thank you for continuing to create quality content!
