There is another rock sitting alongside a chief artery about 25 miles NW just beyond Schaumburg. Silly to give these things a name.
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.

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

Surprised to see `ExtraORDinary Rock` missing => 50-tons, that's got to meet the bar for extraordinary.
Ditka
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'."

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.

Naming things after living people is bad luck
I like 'Da Rock' because it reminds me of da orks from Warhammer 40K
I like "Orchard Rock" because it's not some stupid reddit'ism.
How is 'BDU' not the top choice?
Shakin my damn head where is "Rock and Roll McDonald"
So they completely ignored the discoverer's suggestion. Humbug.

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

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.
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.
That rock couldn't have been found by a better guy.
Even a rock has a soulmate! Not I.- /s
They should name it after this guy, the Pitelka rock.
Surely it has to be “Boulder McBoulderface”?

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

Can have the best of both worlds.

Da Rocky McRockface

Rocky McRockface is the perfect name and gets my vote.
Came here with that same name in mind. It would be a stone cold crime if that wasn't picked.
I wonder if there'll be an episode of Hello Internet on it.
Missed opportunity to call it "Rocky Bouldoa"
That would be a slam dunk winner if it was the airport in Philadelphia.
Should name it Dwayne Johnson and never explain further.

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.
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

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.

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.

O’Hare “Rocky” Dolomite

"Mother's Love"

Because, we so often take it for granite.

Is a 50-ton boulder rare or super-rare?
Not from the look of it.
Dunno, but I haven't ever come across one on my property.
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.

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.

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.

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.
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...

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.
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.
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.

[0] https://en.wikipedia.org/wiki/Madison_Boulder

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

TIL there's something called a short ton.

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.

As an Australian aware of Chicago's Irish heritage and the implied weight balancing our antipodean clime, I'd suggest "Tip O'Dea".
Glad they included a video of moving it. 50 tons is close to the limit of a typical boom crane.
