Geology of the Grand Canyon and the Great Unconformity

Learn about the stratigraphy of Grand Canyon National Park and different types of unconformities. The Great Unconformity , spectacularly exposed in the Grand Canyon, has been linked to the evolution of life and a global glaciation, called Snowball Earth.

Awesome information, thanks

Thanks for sharing your videos. I really enjoy them.

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 :)

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.

[@granodiorite9032]

Do you remember the rough location in Colorado? I'm interested

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

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.

My jaw dropped when I looked that up

[@jdfehrenbach]

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

Annoying cuts

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

Lol you admitted to a GLOBAL FLOOD
