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...

In “original” England they did as well.
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.

here’s a picture of the actual rock - and digger! phew!
> 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.”
But as a resident of the Chicago area, I’m partial to Da Rock

• Sweet Stone Chicago
• No ORDinary Rock
• Chicago Rocks
• O'Rock
• Orchard Rock
• Da Rock
So deciding between the two, Orchard Rock is my pick! It's subtle, but the plaque can explain it.
Then in generations to some, old people can explain that Dwayne Johnson was the King of Wrestling and then became King of Hollywood.
ORD as an acronym? O Rock D

Because, we so often take it for granite.
I had no idea that would be rare, what makes it relatively rare?
I'm speaking in volume. I'm not sure of the mass of these boulders.
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.
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.
FYI, this refers to "Large boulder the size of a small boulder" in 2020

TIL there's something called a short ton.
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.
Maybe that’s too Philadelphia.

"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'."
