The Massive Asteroid Impact That Created Chesapeake Bay

#chesapeakebay #northamerica #asteroid #asteroidimpact #chesapeake #impactevent

Chesapeake Bay has an asteroid impact to thank for its formation. This impact was the largest to have hit the North American mainland to our knowledge, and it was so powerful that it shattered rock over 8 kilometers deep when the bolide struck.

The Chesapeake Bay is such an important feature of Virginia... I'm surprised that I never learned about its meteoric origins before. Awesome fact to learn.

Growing up in Hampton Roads we actually learned a tiny bit about the impact.

Here is something else interesting that relates to this impact: tectite strewn fields confirmed to be linked to the CB impact event have been found on the border of South Carolina and Georgia, and as far away as Texas, half a continent away!

I've driven over the Chesapeake Bay Bridge-Tunnel. As you have discussed non-Australian sites before, can you make an episode about Crater Lake in Oregon? It has a unique history.❤ Glad you're back and feeling better.

as someone who lived in this region for most of my life, i 100% appreciate the look at it's geologic history. i had no idea it was an impact crater! the coastline it created is absolutely wonderful. i lived in St. Mary's county for the better part of twenty years, and i absolutely loved how no matter where i was i could be no more than five minutes from water's edge. thank you for this!

[octavianova]

small correction: the estimated speed of the impactor was 17.9 km/s, not 179 km/s <3 I had to check just cuz a speed that high would directly imply an interstellar origin since that's dramatically higher than solar escape velocity, and sure enough, you seem to have misplaced the decimal point on accident :p

[bobbiezarate]

Oz! This is cool as...
I had No idea there was an impact crater so close to us here in North Carolina! Mind blown, Again 🤯

[harrietharlow]

Thank you for putting this up. You did a great job describing this.

[ricklyle]

Excellent content. This is the first time I have heard of this. Keep up the good work.

YAY! We made it <3 I learned about this in high school back in the 90's. Virginia is made up of 3 regions Tidewater, Piedmont, and the Mountains. It was theorized that the tidal wave gouged everything from the Piedmont to the sea, and that's why we're so flat. i can't believe we made it.

[helmutzollner]

That is interesting.
Considering the map of the Eocene the tsunami from this impact could have gone through the thefts ocean all the way to Central Asia.

I live right in the center. It's Chesapeake btw, and I always wondered why there were so many meteoritic rocks

[magicmusic]

I have read many books where the setting was Chesapeake Bay, and indeed one of my favourite songs from the 70's is Moonlight, feels right. One of the lyrics is Chesapeake Bay. Always fascinated me how I was drawn to that area. Well, now I know! Geology! ☺ BTW I am an Aussie!

[Salts]

Just checking if you're aware of the Deniliquin Structure?
If I've missed it, then let me know, if not, check it out, it's our own version of Chesapeake Bay.

[morrismurray]

Just driven the Nullarbor and saw these huge cliffs that went almost from Esperance, ran parallel to the Nullarbor road for a few hundred kms and then became the Bunda Cliffs. How about an episode on what caused this huge long cliff?

[kenbrady]

Thank you for showing, tacitly, how the current residents of this ecosystem with deep history are clueless about its significance.

[acm]

This area has some really interesting features related to this impact, all the way west to the edge of Richmond 90mi/144km inland. Evidence of the tsunami creating massive piles of land debris spread out in radial and ripple pattern all the way to the “Fall Line” where the land abruptly drops down from the Piedmont plateau into the flatter terrain of the Tidewater.

[robertboykin]

Just south of the Bay bridge, is [ or was ] a deep place that was named Devels hole, 110 ft deep.. I wonder if it had anything to do with it.

[No_Fuse]

I can't tell if you are saying cheesespeak bay, or Chesapeake bay, either way, I'm calling it cheesespeak bay from now on. Great video as always my guy. 👍
[EDIT] Let me add, I'm hard of hearing.

[shanascontrino]

So with impact theory wheres the traps on other side?
