The Impact Crater Beneath Chicago; The Des Plaines Crater

Beneath a section of Chicago, there is a hidden several mile wide impact crater. This might initially seem like a crazy claim but it is true, existing underneath the city of Des Plaines. The only reason it isn't highly visible today is due to sediments emplaced during extensive glaciers during the last 2 million years. It is for this reason that I will discuss when this crater formed, what evidence we have, and what immediate effects its formation had.

    There's a larger crater SE of Chicago and due south of Gary in Kentland, Indiana. It's called the Kentland Crater even though the crater no longer exists. What's present is the rebound dome of rock strata that was shoved down by the impact then shot upward to leave the formerly horizontal strata standing staight up. The dome's diameter is 3-4 miles wide and around 800 feet in height. Geologists believe it had lost another 900 feet in height xue to erosion and glaciers. It was discovered by two farmers that found solid rock beneath 16 inches of soil. They opened up a rock quarry to discover verticle layers of sandstone, limestone and coal. Geologists finally figured out what caused that in 1972. The quarry is still in operation and has a website showing the exposed layers. They also set outside the fence small rocks that show shearing for tourists to take home.

    Never knew we had an impact crater. I did know that we have a mid-continental divide, separating the Great Lakes Basin from the Mississippi Basin, a low ridge that forms the Des Plaines River valley. It was pierced by the Illinois & Michigan Canal, and later the Sanitary & Ship Canal, at Chicago Portage. And the Des Plaines River itself is a result of a massive flood, when Glacial Lake Chicago broke through the bank and the torrent carved out the current valley.

What with 9.0 earthquakes and subsequent giant tsunamis, solar storms, super volcanoes, sudden ice ages or runaway greenhouse effects and occasional asteroid impacts, it is not surprising that we don't detect evidence of advanced civilizations elsewhere in our galaxy. In fact, it seems we've been incredibly lucky to have the time to develop as far as we have (technologically, if not civilly) without being wiped out entirely or at least knocked back to the stone age. 😕😱💀😳

    There was a geological study using core samples in The Black Sea, and mapping the area where it meets The Bosphorus, which has revealed strong evidence that The Black Sea filled slowly over a long period of time rather than in a deluge the way The Mediterranean did. Rather than water pushing through from The Mediterranean and forming The Black Sea, The Black Sea was a massive lake that slowly rose until it met with The Mediterranean and eventually became salty through the waters mixing over time.

Since so much of Illinois has beef with Chicago [mainly political, since it is a speck of blue in a sea of red], things and people not in Cook County cannot be attributed to or blamed on Chicago, regardless if the story is positive or negative. Other Large Cities that make up a large chunk of their state have similar things, like NYC and Upstate NY.

    Honestly any crater that causes that peak in the middle is terrifying. It basically makes our crust into a liquid. Like a drop in the ocean. What an incredible amount of force. Thankfully we've been able to map most of the potential impactors that could be that destructive, and we don't think any are coming any time soon. I honestly think that's one of the coolest things done in my lifetime. We went from Pluto being a planet to the Kuiper Belt being discovered and an incredible survey being taken of near-Earth asteroids and us figuring out that we aren't, in fact, an endangered species. Well, unless we screw ourselves.

    It would be interesting know types of rock were created when that asteroid pounded into the seabed? If it was coal there might be diamonds

    You pronounce Des, with the "s". Not like Des Moines. I'm very glad that this event happened long ago, because I live around 15 miles from Des Plains. You better be over 1,000 miles away.

    Have you looked at Hudson bay ? Nastopka Arc . It is a prominent, near-perfect circular arc, covering more than 160° of a 450-km-diameter circle. Is that a old impact

    No, it's not an impact crater, even though it really looks like it on a map. I have this from a geologist at the Ontario Geological Survey. If you look up Nastapoka Arc on Wikipedia, there's reference to a paper by Dietz et al, describing an extensive search that was made for evidence of an impact there, with negative results.

    There are no impact proxies in or near the Nastapoka Arc and no obvious gravity anomalies, which pretty much rules out an impact origin. On the other hand, there is no alternative explanation on how it formed. Nobody knows why it exists.

    @@Itsjustme-Justme IIRC, the current theory is that it formed about 2 billion years ago as the North American craton accreted a bunch of micro-continents, forming much of the Canadian Shield.
