SW Michigan Hunt for Lightning Stones, Yooperlites, and More!

I rarely get to this part of the state so this was an extra fun day for me. I met up with locals Chris and Chuck as well as my friend Jonathan.

Powerful group of Michigan rockhounders. Michigan proud! Knowledge evident🥰

[@Gene.Guazzo]

I’ll second that! Would be great to tag along with that group and soak up their experience. They’ve done a lot of tumbling with those examples we saw. Just eyeballing it and feeling the weight of it they could tell if it would shine up or not.

[@MichiganRocks]

It's still just a guess in some cases. I'm going through all my tumbles from last summer right now and I did have several duds.

[@Gene.Guazzo]

@@MichiganRocks It’s been so hot in the desert I haven’t been able to get out so I spent one of my weekends doing the same. I culled my rough down by about a third. Can’t believe some of the stuff I brought home. Cold water agates is a new term for me. I see a consistency in what they are picking up. What did they say they tumble out like?

[@MichiganRocks]

@@Gene.Guazzo I don't think we discussed how they tumble. Nancy and I were on a Lake Superior beach today and were cold even with sweatshirts on.

@@MichiganRocks it really is! That was my first time in the Keweenaw. I can’t wait to go back. We also made a trip to an abandoned quarry and mined for greenstone! It’s amazing the different rocks and minerals you can find sprinkled throughout Michigan.

[@brightpurpleviking]

@@TenSeventeen what’s your favorite SW beach for rock hunting? We were just up from indiana and rock hunting in Glenn because we couldn’t find a rock beach near South Haven. We hope to go again in the fall or spring.

[@TenSeventeen]

@@brightpurpleviking I’ve spent most of my time walking along warren dunes state park, farther south than south haven. The geology isn’t anything special, but there is a glacial moraine that intersects Lake Michigan just north of the park property, leads to some interesting finds.

The lightning stone polished beautifully!

[@MichiganRocks]

Yes, they shine up really well.

[@brightpurpleviking]

I was just there this past weekend! We found some amazing finds. We found some excellent lightning stones, one lightning stone that had a two inch ammonite fossilized in it, one very tiny pudding stone, and some antique blue and white China chunks. Found some beautiful petosky stones. There was one rock that I’ve never seen before. It is dark black and had nice chunks of a pale sulfur green-yellow. So strange! No clue what it is. Also…we learned a thing or two about appropriate foot ware. Ouch! We wore crocs thinking we could clean them out easily. Wished we had boots instead.

[@MichiganRocks]

The black and green one might be porphyritic basalt. It sounds like something I find quite often.

Mine is a metal spoon on a piece of PVC, but that's not good for prying either.

@@MichiganRocks I went through a couple spoons. Bent them back and forth too many times and snapped them. I found a heavy duty one, it's on a piece of cedar now and I can pry stuff now without it bending. Still rocks fall off of it, I like his scoop design and can see why it would be better than most. Oh and I do like that it folds, mine doesn't so every so often it ends up sitting propped up next to my garage and I forget it. I might have to get one just to leave it in the car for days when I'm scatterbrained.

I Hit Pier Cove, Pilgrim Haven, Deer Lick Creek, Van Buren State Park, and the surrounding areas. Maybe we were at the same beaches! Anyway, I found a variety of amazing rocks and fossils! Another thing you can find on SW Michigan beaches is lake coal. Yes real coal. Since it is so light weight, it doesn't dwell in, at, or near the water. It is found away from the water floating on the sand. It stands out from wood charcoal, as it has a shiny luster, and is heavier. Anyway, glad you came to the area, and happy hunting

I find coal up here on Lake Huron too. I'm pretty sure it is from ships or one of the industries that burns or burned coal in the past. I find it quite often at Rockport, which is an old quarry.

Stones with the geode pockets: are those “safe” to tumble? Meaning will all the crystals fall out? Something about them makes them seem fragile.

@@MichiganRocks I didn’t know you were going to get so deep on my, but I’m somewhat of a philosopher myself 😉

[@Theodore_von_Schwarzenhoffen]

That's awesome. What wavelength UV are you using? I'm assuming it's down around the 365nm range?

[@MichiganRocks]

Yes, 365nm.

[@Theodore_von_Schwarzenhoffen]

@@MichiganRocks Nice! I gotta get one. Thank you!!

[@NERocks73]

Could you list the grit sizes on your cabbing machine? Having trouble with some scratches on mine, wondering if I'm missing a grit.

[@MichiganRocks]

The grits are: 80, 220, 280, 600, 1200, and 3000.

[@NERocks73]

@@MichiganRocks Thanks so much.

[@AulThingsOutdoors]

What lights do you use for finding yooper lights? I have a few bit none that provide the glow that yours does. Any info would be amazing. Please and thankyou

[@MichiganRocks]

I don't know what all of Chris's lights are, but mine is a Convoy S2 365nm light. This is what I have: kingsleynorth.com/convoy-s2-uv-led-flashlight.html?queryID=4d322635e6ff95e490b6f3f429ca80be&objectID=11500&indexName=kingsleynorthenglish_products?ref=robertabram1& (affiliate link) kingsleynorth.com?ref=robertabram1& (affiliate link)

Where did Chris get that SWEET t-shirt???

[@MichiganRocks]

No idea.

[@adventurecooper]

I picked it up at Copper world in calumet. Thanks

[@MichiganRocks]

@@adventurecooper Hey, Chris! You're still reading the comments, huh? Thanks for taking this one.

[@shaewilson4503]

So is the cold water agate what you’ve been calling the mystery rock?

[@MichiganRocks]

No, not at all. The rock I call mystery rock is found on Lake Superior. It contains chalcedony, but I'm not sure it's 100% chalcedony. There are usually about four different colors in it, and they're mostly dark colors. They're also not fossils.
