Curious. Have scientists ever drilled into one of these sights to get to the meteor?

[Southside_Chicago_Republican]

I lived for some years in that area and didn’t know about this.

The meteor is often vaporized and ejected in the process.

Explorers drilled in Meteor crater in Arizona for years, looking for a massive iron/nickle deposit. They never found any large mass. Just small bits and pieces. Biggest was a couple of yards across.

Yes, Shoemaker, of the Shoemaker-Levy comet that plowed into Jupiter in the 1990s, drilled into Arizonas Meteor Crater and found tons of meteor debris. Here? Don’t know.

Ends up the meteor that in Arizona plowed into the ground at an angle. When they tried to drill down, they found nothing. Sideways, they found lots of remnants.

Part of it is on display at the museum beside the crater.

Meteor Crater, east of Flagstaff, Arizona. Been there many times:

Cool site. Thank you for posting this.

So that is the boiling burning pit of ash and hell Hillary climbed out of...

Chesapeake Impact Crater is fairly big (85 km) and fairly recent (35.4 Mya).

The biggest Bolide crater in the US is the Chesapeake Bay impact 35 million years ago. It fell north of where the Delmarva peninsula opens to the Atlantic. It blasted so much water and soil out from the impact zone that, as the water rushed back in, it changed the orientation of the James and York River mouths to point north easterly towards to central point of the impact instead of south easterly toward the opening of the bay. Norfolk Naval station probably owes its deep sheltered harbor to this event. https://pubs.usgs.gov/fs/fs49-98/

Beat me by 4 minutes! Lots of information out there about how disturbed the soil is today from this event. Digging a well within the ring you show yields brackish water with many dissolved metals because the geology was so profoundly remodeled.

How do you pronounce "Des Moines"?

Da Moin.

By the same logic, how do you pronounce "Des Plaines"?

Da Plane! Da Plane!

(Sorry, 1970s "Fantasy Island" TV reference.)

[BiteYourSelf]

SunkenCiv beat yah to it.😁

[poinq]

I live there. The locals pronounce it phonetically Des like Mess. And planes like Plains.

I’m in N. Central Illinois and I’ve never heard of lt.

Similar, but I think larger, buried crater called the Manson Crater in Iowa.

These craters in prairie soils are essentially filled in and can’t really be seen with the eye.

It takes some underground examination of bedrock like deep well drilling to discover the bedrock anomalies.
