here’s a picture of the actual rock - and digger! phew!

Stratoscope 2d ago
That is a wonderful article!

> Over the years, Pitelka has rescued some of these rocks and deposited them at his mom’s five-acre property, including a large hunk of limestone that, when he dumped it out of his truck, split in half to reveal a perfect trilobite fossil, convex on one side and a matching imprint on the other.

> “I was so excited to hear that the right people got involved,” he said. “I’m absolutely ecstatic it’s going to be on display. For me, as an (excavator) who loves boulders, it’s the coolest thing that people understand its historical significance and appreciate it.”

Man this guy found his life’s calling. Love to see it.
elcritch 1d ago
I love the ambiguity as to whether his mom wants the rocks dropped off in her yard or not. ;)

I know a lot of people who live in apartments but have a collection, usually classic computers, stored in their parents house. Hell, I was just talking to a guy few weeks ago who was lamenting how his parents threw out his "junk" pdp11 years ago.
mathgenius 1d ago
They should name it after this guy, the Pitelka rock.

That rock couldn't have been found by a better guy.

I did but honestly didn’t see it. My connection was struggle to load all the billions of ads.

I don't see it. I do see a blocked twitter embed and when I click the link to that I do see a rock https://x.com/cbschicago/status/2111193918909903146

Thank you, great read.

Surely it has to be “Boulder McBoulderface”?

samgranieri 1d ago
I was going to suggest just this! I love Boaty McBoatface.

But as a resident of the Chicago area, I’m partial to Da Rock

aceazzameen 1d ago
Can have the best of both worlds.

Da Rocky McRockface

tanseydavid 1d ago
Rocky McRockface is the perfect name and gets my vote.
MegaDeKay 1d ago
Came here with that same name in mind. It would be a stone cold crime if that wasn't picked.
dmd 1d ago
Gneiss!
senectus1 1d ago
Missed opportunity to call it "Rocky Bouldoa"
Mountain_Skies 1d ago
That would be a slam dunk winner if it was the airport in Philadelphia.
underdeserver 1d ago
I wonder if there'll be an episode of Hello Internet on it.
tjwebbnorfolk 1d ago
I think this is the only valid name
Stratoscope 2d ago
Here are the name finalists:

  • Sweet Stone Chicago
  • No ORDinary Rock
  • Chicago Rocks
  • O'Rock
  • Orchard Rock
  • Da Rock
"No ORDinary Rock" and "Orchard Rock" are the winners for me. They both pay tribute to how O'Hare got its IATA airport code in the 1940s, when it was called Orchard Field.

So deciding between the two, Orchard Rock is my pick! It's subtle, but the plaque can explain it.

swingandamiss 1d ago
I like "Orchard Rock" because it's not some stupid reddit'ism.
lbriner 1d ago
Just call it "Dwayne Johnson"?

Then in generations to some, old people can explain that Dwayne Johnson was the King of Wrestling and then became King of Hollywood.

adzm 1d ago
Naming things after living people is bad luck
jhatax 1d ago
Surprised to see `ExtraORDinary Rock` missing => 50-tons, that's got to meet the bar for extraordinary.
robotnikman 1d ago
I like 'Da Rock' because it reminds me of da orks from Warhammer 40K
firesteelrain 1d ago
Or ‘Da Bears’ trope from the SNL Skit
phlakaton 1d ago
So they completely ignored the discoverer's suggestion. Humbug.
whycome 1d ago
Wish I saw some of the larger list. This still seems weak.

ORD as an acronym? O Rock D

O’Hare Rock Dolostone O’Hare Runway Dolomite

Rocky.

Da Dolo

Sounds like something from the old Bill Swerski's Superfans sketches from SNL.

"Alright sooperfyans, next question. Who would win: Coach Ditka, or a 50-ton boulder flying down da side of a mountain?"

"Oh, dat's easy, Dit..."

"Hold ahhhn, hold ahhhn! Da boulder is also named 'Ditka'."

anonymousDan 1d ago
I like it. Ditka Rock has a certain ring to it.

"Mother's Love"

Because, we so often take it for granite.

syspec 1d ago
Interesting, the construction worker who found is said he never found one that big in all his years working in the field.

I had no idea that would be rare, what makes it relatively rare?

firesteelrain 1d ago
Largest dolomite rock ever found maybe ??
bcaulfield 2d ago
Should name it Dwayne Johnson and never explain further.
cestith 1d ago
Or Rudy Ray Moore.
chrismcb 1d ago
That boulder must be the size of a large boulder.
SideburnsOfDoom 1d ago
This is the answer.

FYI, this refers to "Large boulder the size of a small boulder" in 2020

Is a 50-ton boulder rare or super-rare?
crisnoble 1d ago
In chicagoland, yes. For someone who moved there from California, it was strange that rocks hardly larger than a human warranted school field trips and plaques. Perhaps it is geologically cool, but I was unimpressed as a 6th grader. https://live.staticflickr.com/65535/53236492797_60069bde90_b...
waltbosz 1d ago
I thought the same thing. My back yard is full of huge rocks. Nothing quite that large, maybe 1/3 of that size. A few doors down there is a boulder twice as big as the O'Hare one.

I'm speaking in volume. I'm not sure of the mass of these boulders.

quickthrowman 1d ago
In an area that was covered by a glacier in the last 20k years, yes.

Chicago was covered by ice during the most recent glaciation, which means that boulder is probably a glacial erratic covered by till leftover from the movement of the glacier.

rags2riches 1d ago
It's not just the fact that the area was covered by ice. The local geology is also a factor.

Glacial erratics are everywhere in Scandinavia, which also obviously was covered by the ice. Small ones, like in the article, are scattered all over. Large ones weigh thousands of tons and may often be mistaken for bedrock.

I suspect there are other areas in North America where that's also true.

quickthrowman 19h ago
There are no mountains in Ontario or Saskatchewan and that is where the glaciers came from, there’s only the exposed bedrock of the Canadian Shield.

If you're ever in the area of Madison, NH and have absolutely nothing else to do, the Madison Boulder is kinda neat. [0] It's a little bigger at about 5k tons.

stutstev 1d ago
With New Hampshire mentioned, I must make mention of one glorious boulder that sits alongside Rumney's Quincy Road[0]. This is worth checking out if you're visiting the Plymouth area. Street View doesn't do it justice.

> It weighs upwards of 5,000 short tons (4,500,000 kg).

TIL there's something called a short ton.

defrost 1d ago
If you're in the USofA it's the same 2,000 (US) pound ton you've always known.

For those of us elsewhere on the globe it's that non metric weight we call either a short ton or a US ton.

The OG ton, also known as the imperial ton or British ton is some 2,240 avoirdupois pounds that's been "standardised" (plus minus some obscure fuzzing) for some 700 years or so.

“A large boulder the size of a small boulder"

https://time.com/5772944/large-small-boulder/

entrope 1d ago
I was going to suggest something in that vein, perhaps "a giant boulder the size of a large boulder" to distinguish it from its Coloradan cousin.
mindslight 2d ago
There's something about finding huge rocks in the ground while digging that makes you just want to take them out and like, use them for something? The last one I found I had to make myself leave it there (well I moved it over a foot so a pipe didn't have to go around it). Like no, it has sat here for thousands of years just fine, it can keep sitting. Glad to hear it applies to 50 ton ones, as well.
acomjean 2d ago
In New England they made stone walls out of them. Of course most where smallish

https://www.outdoors.org/resources/amc-outdoors/history/hist...

In “original” England they did as well.

https://en.wikipedia.org/wiki/Dry_stone

mindslight 1d ago
Oh sure, I'm definitely familiar with those. The weird ones are in forests, a reminder that an area used to be clear and then was left to grow back.

The walls of stones were the result of collecting stones that were near the surface from what I understand (maybe plow depth). I was talking more like bigger stones that were buried several feet under the ground that could just stay where they are (when you fill in the hole), but for a compulsion to treat them as things.

Glad they included a video of moving it. 50 tons is close to the limit of a typical boom crane.

When Toronto had to name their team, I’m sure that the success of Jurassic Park helped the finalist (Raptors) win. I’m surprised “Rocky” didn’t make a finalist here (via Project Hail Mary).

Maybe that’s too Philadelphia.

Tangent time: I've got a smaller one in my yard, and I've got a set of feathers and wedges to avoid having to dig it all up at once. Here's a video of someone using feathers and wedges to split granite.

Pictures or it didn't happen?
dbcurtis 1d ago
Years ago, a company that I worked for had a huge boulder in the parking lot area that had simply been built around. At some point, facilities decided they were going to remove the boulder. Employees printed up some tee shirts that said "Save the BFR". Because, you know, it was a big rock.

What means "prehistoric boulder", are not essentially all boulders prehistoric? I just don't know what a historic boulder would even mean. Something in Raiders of the Lost Ark?

This boulder was broken off and shaped by the ice thousands of years ago. New rocks fall off mountains all the time.

As an Australian aware of Chicago's Irish heritage and the implied weight balancing our antipodean clime, I'd suggest "Tip O'Dea".

PS. If visiting Chicago check out the Lincoln Park Conservatory, an amazing historic plant collection with one of the world's best ferneries, very close to downtown. https://www.lincolnparkconservancy.org/projects/conservatory...

powerbroker 2d ago
There is another rock sitting alongside a chief artery about 25 miles NW just beyond Schaumburg. Silly to give these things a name.
Stratoscope 2d ago
There are big rocks everywhere. But surely we can be allowed to have a little fun?
powerbroker 2d ago
OK, OK. just drag it up to Schaumburg. Put it next to the other rock. Then call it 'micro-henge'.
Stratoscope 2d ago
That works for me! Can you help me drag this 50-ton rock?

How is it possible that NONE of the candidate names refer to Colbert? Especially given his time with Second City.

https://en.wikipedia.org/wiki/Cultural_impact_of_The_Colbert...

tptacek 1d ago
Colbert is not a Chicago figure. You'd have to remind the median Chicagoan who knows who he is that he ever spent time here. You might just as easily name it after Bob Odenkirk.
dhosek 1d ago
And at least Odenkirk sounds like he’s from Chicago (because he is). Colbert’s time in Chicago was a short part of his life.
tptacek 1d ago
Berwyn, technically! Our neck of the woods. :)
dhosek 1d ago
He grew up in Naperville. Wikipedia says he was born in Berwyn, which I assume just means he was born at McNeal, but I don’t think he ever lived there or there’d be a bigger deal made of it by the local gentry. But that voice is hardcore inner suburbs/southwest side. I had no difficulty believing Jimmy McGill grew up in Cicero.
nonethewiser 1d ago
I dont get it. Does he have some association with large rocks or something?
