Geology of the Grand Canyon and the Great Unconformity 

Awesome information, thanks

this was a helpful video thank you

I love the way that geology transcends nations and yet, is often as simple as basic observation - pick up a rock and take a look. That explains why I take so long on Grand Canyon hikes. I'm not lazy - just busy looking. I do have some Zoroaster granite on my bookshelf, from the bottom of the Grand Canyon. But only a small piece - I was well aware I was going to have to carry it all the way back up :)

Nice

Taken a quiz right now and my boy right here is a life saver 😎

Thanks for sharing your videos. I really enjoy them.

8:47 direct "Descendants". Just a friendly note from your favorite supervillain, The Stickler.

Solid information, but the pop culture cuts were really distracting.

Can you give me a rough map of the extent of the Vishnu schist? I've come across a very similar outcrop of rock in western Colorado and am feeling a bit puzzled.

👍👍👍👍👍

Have you looked at the Olive Grove in Turkey, after the earthquake about 1 month ago? They look like a mini grand canyon. Can Grand Canyon have been made that way? I know that they tell us it's made of water erosion, but I think water erosion should look smooth. Grand Canyon is nothing but smooth, it looks like it was made yesterday, or maybe 10,000 years ago at best. Pyramid and sphynx erosions look older than Grand Canyon.

Annoying cuts

How do you have a billion years of missing time across the whole planet - glaciation would have had to take place across the whole planet

Your snowball earth image is wrong. That was not the continental configuration at that time.

Lol you admitted to a GLOBAL FLOOD
