Hiya! I also live in Northern Minnesota! In the Island Lake area. I’ve found a lot really neat rocks in our fenced in yard that look a lot like some of these. My wife found your channel, we’ve just got into rock tumbling! We had a dull first go, haven’t tried since then. So we’re just doing the learning now and try it out once we got all the materials, and have found our motivation. 👀 Thanks for tips/tricks! 🙌🏼
Wow. You should get that lock checked out by a marine archeologist. Might be something there. Who knows, maybe you stumbled upon relics from an old shipwreck. Perhaps that was attached to a treasure chest at some point in time 🤔 😳 lol
I think that's called a 'pancake' padlock. You can see nearly identical examples(cast iron Imperial like yours) on Worthpoint. Still couldn't get a fix on how old ... but I'd wager nearly a century. Nice finds...you guys up there have some nice rocks...glaciers weren't as kind to us.
@@AgateAriel While it's impossible to say exact years " Near a century" is close enough. Woudn't be a bad spot to take a metal detector out to! The giant nails would be railroad related,, and the fossil is Fossilized coral. There is a type of that coral called Honeycomb Coral, and I look for that stuff anytime I see a new pile of river rock.
