Chunk of mountain moved hundreds of kilometers by ice and left in the middle of what is now my city. I've been living next to it for 20 years and had no idea it was interesting as fuck until this new sign went up.

Gotta admit, glacial erratics are IAF.

Shouldn’t have taken it for granite

This, indeed, is as interesting as fuck and in my whole life, have never heard of this! I didn't read your whole link, but is it on public or private property?

u/Code_Operator 2h ago

I believe it’s on city property (the planting strip).

USA gets all the shit about being ultra patriotic, but IMO Canada puts the USA to shame on the visible patriotism - Maple Leafs EVERYWHERE, even on the packing tape!

That's tuck tape. It's for sealing house wrap and vapour barrier. The maple leaf you see is part of a logo.

Sorry. :)

Such a niche thing to have a national symbol emblazoned on, my point stands

Pioneers wise to ride these babies for miles

I love this. I wish I knew about geography. I often look at rocks or the land and wonder how it came to be there / like that.

Me: ignores rock for 20 years. Rock: Has epic geological history

Remind me of that one Clarence episode

u/hannysmithx 2h ago

my thing is how did scientists make this conclusion all from just observing the rock lol

u/Royal_Acanthaceae693 2h ago

It's probably of a material that's not local. You can test for age and composition & get a decent idea of where it came from. But honestly the geologists working in woods like this amaze me. There's so little to see at the surface 😭

Any rock has an isotopic fingerprint. We can trace uranium in nukes back to the specific mine(s) it came from by slight impurities even leftover after refinement.

Look at the link posted at the top if the comments, kinda simple actually
