- KINGSLEY NORTH -
Kingsley North is a lapidary store in Michigan's U.P. They make a great cab machine and sell many other brands too. They have a huge selection rough rock, tumblers, grit, jewelry supplies etc. at good prices. I buy most of my coarse grit from here in 45 lb. bags. It's the best price I have found. If you buy using the following link, I make a small commission.

I love it when you have the geologists on.
they are awesome! thanks
They seem to be everywhere lately!
Beautiful day Rob, always enjoy your adventures and all the information too is amazing, always learning something from your videos. I appreciate what you do and your hard work! Thanks for inspiring!
When hunt with geologists, I usually learn something too.
It was funny when everyone sat down and started sifting through the pebbles. A lot of times, when I think I've found something cool, but it turns out to be nothing special, I end up thinking, "Hmm, i wonder if there's anything special underneath". And I'll start sifting through the smaller stuff. Then i have to tell myself, "Morgan, stop it! You'll be digging for days. Move on!"
On one hand, it would be fun to see the rocks underneath that no one sees. But as you said, that takes a long time. On the other hand, you can see a lot more if you keep moving. But those rocks have been looked over by many more people. It's a dilemma, so I go with what makes me happier. That's walking for me.
Nice. It's fun seeing a place I've been to.
Another cool beach and some great finds. Thanks for sharing. Cheers from the 920 of Wisconsin.
Back with the team! Gonna be good.
We're mostly rockhounds watching ur vids so not many say this "Awesome drone footage, camera work and editing skills Rob! ☆ Great video!
I get a few comments on those things, but I never mind hearing it again. That drone has been a lot of fun. It's a perspective that is so different from being on the ground. It's the footage that I'm most excited to see when I get home too.
This was lots of funs. Good re-watch value. ;-) Love those beautiful tiny agates. I like to take zoomed-in photos with my macro lenses. And these would be great subjects. Just lovely.
I have to admit that I prefer bigger agates, but it's fun to find the little ones too. This winter, I need to go through my whole collection of self collected agates and do something with them. I think I want to make a jar or wine glass or something filled with all the tiny ones.
Very fun video! Thanks guys!
So many new names, but very helpful. Thank you all for such a fun and educational film😊
You're welcome, Kari. I appreciate you watching all of them.
I want to go here so bad
Glad you liked our home beach. I agree about sitting and pawing through the tiny rocks. Drives me crazy too. I call those little ones chippies or fragates.
It was fun for a few minutes, but I just like to move more than that. I also like to look at bigger rocks because you're never going to find a prize agate in the tiny pebbles.
A very beautiful day! You all found lots of really cool rocks!😍🥰😇👍🏻👍🏻👍🏻
First! Back at my favorite local park! Well, we have a “Gratiot” park too, but mine is just north of Port Huron.
Both Gratiot parks are good, but I like this one better.
Good show Rob.
Took the family to Norwood to watch the sunset on Sunday. Found a couple small agates, a bunch of fossils and enough cool chert to fill a couple barrels on the tumblers. Thanks for the tip.
You found agates at Norwood? That's awesome. The banded chert is thick there.
@@MichiganRocks Just a couple small pieces. Have you ever hunted the beach by Susan Creek Nature Preserve near Charlevoix?
@@baldwinjeremy182 No, I haven't. Is it good?
@@MichiganRocks I'll PM you on IG. Don't want to get too specific here, lol.
Woo a learning day👍. Guys after my heart,sit down sift threw the bottom😉.
I'm not that guy. That kind of drives me crazy, but it was fun for a few minutes.
Nice littles. Great identification information, thank you for sharing.
Sounded like a great time!
Seen that sandstone looks like a map I totally agree.
Wow. Very gorgeous place and cool finds
Always fun and entertaining !
Still laughing... Awesome video! Thanks.
Rob, at 2:00 you said, ‘I thought it was something special, but,,, ’ when showing the rocks you’d found, talking especially about the unakite. I was immediately offended, thinking ALL rocks are cool, and beauty is in the eye of the beholder! I love them all, just some more than others. 😂 Would have loved being up there with you guys, even if I didn’t find ‘anything special’, just to be out in the sunshine and fresh air, with good company. Heck, I don’t even mind being out alone! Thanks for recording and sharing your day with the beautiful stones and good, semi(?)-professional company. ANY day on the water searching for rocks is a good day!😂
Sorry to offend you. I have to admit that I don't love all rocks equally. I think it would be kind of strange if anyone really did find them all equally special. I think the definition of special makes that impossible. For what it's worth, I do really love unakite and have probably polished more of that than just about any other rock.
@@MichiganRocks I’ve noticed you really love your Unakite😂😉! There are definitely some that I like more than others, and really like finding unusual ones. But the best thing I like? Is being able to be able to be there and look at all the beautiful colors and designs, and thank God for this beautiful world we have! Really like all of your videos, and love the drone shots! Makes me wanna get one! I know your videos must take a lot of work, a lot of time and effort. Thank you!
@@littledabwilldoya9717 I couldn't agree more with you. God makes some pretty amazing things.
I super love that long one you intend to polish. It looks like an ear of corn.
It's a-maize-ing.
Love your channel! Getting into rock hunting because of you
That's the problem with my channel, I'm just creating competition for myself!
Love it. Beautiful little finds. I have to plan a trip back to the UP soon. I'm going crazy not hunting.
This is my most favorite part of the world. ALMOST got there today, but my friend knew better. lol She does not do rocks. I seriously LOVE this place. I remember going down in there when you hadda park way up and haul your stuff down. That road didn't always get to the beach. In fact, the first time I've ever been in there, my friend drove us as far as possible, and on the way out, hit a big rock and ripped off his muffler. lol..oh boy...THAT was a ride home.
The road is pretty good these days. I think just about any car could get in there.
@@MichiganRocks Yeah, NOW it's not a problem....years ago....not so easy. Although there were other spots like that, but they've all been sold to the wealthy that spend a week at their million dollar "cabin".
Nice adventure, such a beautiful day.
TOTAL TREASURE HANDFUL 💖
❤💙💜💖 Educational 🏆 📹
900 million years old sea floor 😃🙂🥰😍🤩
Very very pretty probably in person with fossils to see......
I could sit down a bit, then the sound of the waves and NEW THINGS TO TAKE IN
always pulled me back to walking the sand & looking at the surroundings.
COMPLETELY RELATE.....
Really beautiful beach with some great rocks and minerals! You know if you buy a jar and keep the smaller agates and agate chips in it, it looks very pretty, especially when you get it filled up and you put a light behind it. That's what I do and people love them. Thanks for sharing Rob, and your two sidekicks!✌️🤠
I want to do exactly that. I don't know if I have enough to fill up a little jar yet, but it's about time I sorted them out to see.
Well that sure was fun! The prehnite and thompsonites were beautiful! And Greg's beautiful banded agate was amazing! Lots of really beautiful rocks there, and a great education from our geologists and a beautiful day! Thanks for sharing!
That agate that Craig found was tiny, but so pretty. It's amazing how detailed that banding can be.
@@MichiganRocks Oops, i got his name wrong and its funny because i have a brother named craig that even my grandma called him greg, his whole life! Sorry Craig!
Gorgeous place and awesome rocks as always! Funny story about Lake Superior sandstone- when I was a kid, we took a camping trip to the UP. I saw large fingers of sandstone extending out into the water. My parents thought they'd be slippery and wouldn't let me. Later, as an adult, I honeymooned up on Lake Superior. One of the first things I did was find that sandstone and walk out on it! My rebellious inner child at work! It wasn't slippery, but that water sure was cold!
You rebel! You probably deserved to fall in just for disobeying your parents even if you were an adult. Then again, I've done similar things myself, so I shouldn't judge.
This is such a beautiful beach and the Gratiot River looks so peaceful joining the Lake. I remember walking to the East (right of the River)? the last time I was there and the rocks were so deep then it was hard to walk because you sank into them. We visited during the day once and then again at night for Yooperlites. I found a huge one and quite a few others. Loved the aerial shots too Rob. They definitely provide a different perspective and reflect just how vast this area is. Thanks for sharing.
I was there a few years ago when the rocks were really stacked up and there was a several foot steep drop down to the water. It wasn't like that at all this time.
Good job! The sandstone info was interesting.
9:16 😂I am so glad I am not the only one who will admit to that!
Great video, thanks! Love the drone videos interspersed...
I love doing the drone videos. It's not always possible to do them because I have a really small drone and it doesn't fly in much wind.
What a beautiful place ! Love the green of the woods , deep blue waters and those gorgeous blue green smooth rocks 🤩😍👍
Lots to love in this part of the world.
I was blessed to fly out over the Keweenaw peninsula in late September one year, when the color was in full splendor. It was sunny with a beautiful blue sky, and the water was shining in a tirelessly sparkling frame around the mixture of hues from the different trees. Will never forget that!💗🌈☀️😊
@@MichiganRocks I totally agree ! How blessed you guys are indeed 💖
@@littledabwilldoya9717 Sounds beautiful!
Hematite mixed with red jasper is one of my favorite and most challenging rocks to polish, and I still deliberate with the correct pronunciation, but I know the right way is with the long E. Great look into Michigan's geological history. Thanks so much for sharing.
Most banded iron that I find in lakes tumbles well for me. It might depend on where you find it. I'm not sure.
Rob,
Having a geologist along makes it so much more interesting:)
Cheers,
Rik
I can't always do that, but I'm glad to do it when I can.
I'm always amazed at how many geological people you run into.
It's not really a coincidence. Cody started rock hunting because of my videos, started a website and a Facebook group, and then Craig (the geologist) found the Facebook group.
@@MichiganRocks well Rob; You, Sam, the son in law. Nancy, your sister and all seem to attract a audience all over the world 🌎 and inspired many people to try different things. Cody being one and I'm sure Sam was one of the first to get inspired.. your friend who built the cabinet tumbler.. all the people at your church and so on.. there was bound to be all of this awesomeness.... our creator puts people on paths...IMO
10:04 beautiful “little buddies”. i love teal & olive
The sculpted topographic limestone was beautiful. I have occasionally seen the wind sculpt the sand like that when the conditions were just right. Was the yellow and black object one of the guys was holding a very portable metal detector ?
most likely yes. referred to as a pin-pointer. allows you to narrow the location of the emplacement much more accurately than a large paddled hand held detector, but typically not or not as tunable as the standard hand held equipment so will light up off anything without having a tone variation to indicate what kind of interference its detecting.
@@letsgoracing4849 I’m guessing that is a very compact detector. Typically used by snorkelers and scuba divers.
now that i have watched it fully that isn't a pin-pointer but it does look like a more portable and compact style of basic metal detector
Yes, that was a metal detector. I don't think he found anything with it. I think it might have been an underwater detector.
Will have to make it up that way.So far I love hunting at Fishermans Island State Park in Charlevoix ...no agates but plenty of petoskies.A beach glass girl showed me a marble she found...since I collect marbles..that would have been the ultimate beach glass find! Farther down toward Traverse there is a beach where you can find smelting furnace slag.If you are lucky you will find blue! I dug deep a few years back and found some large green/ grey 8" x 5"+ pieces...in the sand( in the water) near an old pier.
I found a marble once. I thought it was a tiny puddingstone because of the red on it and was surprised to see that it was a marble.
Which way do you hunt at Fisherman's Island? I have gone toward the campground, but it seems pretty picked over. I was wondering if it is any good toward the airport. I have only been there a couple times.
Looks like a wonderful day at a great location. I wish we had made it there during our trip up in august too.
It's a good beach. My sister who lives up there has been doing great on this beach lately.
I watch your videos all the time. You are the Rock Picking King of Michigan! I have spent a lifetime finding every cool thing you can do in the 906. I was wondering if there was a way I could email you personally. Because I have built a tool taugh to me from an old Yooper which will enhance your rock picking capability enormously. But I’d like the world not to know about it.
IL/Yooper Guy.

I'd like to share something interesting 🤔 with you about the prehnite vs thomsonite stone. I bought a handful of a mix of them both from eBay. I soaked them in lime juice with water. The Thomsonite literally almost devolved and became porous and crumbly. It's more peachy with eyes usually. And the prehnite stayed solid, hard and shiny. Super neat difference.😊😊
That is interesting. I didn't know that thomsonite reacted with acid like that. What was your goal in soaking them in lime juice? Were you trying to clean them up?
Been to that beach many times and never found agates. I thought it was mostly flow banded rhyolite, which I love and collect. I missed a lot there! Thanks
I almost always find at least a small agate there. My sister lives in the area and has been sending me pictures of lots of little agate she has found there this fall. I found one of my bigger agates there a couple years ago. It wasn't an awesome agate, but I sure was excited to find it.
Next time I want to go to the southern shores. North shore was not very good for rock hunting. Never found one agate. The locals even said it was hard to find them. But I do have a bucket of rocks to go through when I get home. Keeping my fingers crossed I picked some good ones.
It's not easy to find agates on the south shore either. As you saw here, we really didn't find much. I joked that we found a lot, which we did, but they were tiny. I would not call that a successful agate hunt. It's still fun to find the tiny ones, but it's the bigger ones I'm really after. I haven't hunted the north shore except one really crowded beach in Minnesota once, so I can't really compare. I just don't want you to come to Michigan and expect that you'll easily find agates. There's a reason I get excited about even the tiny ones. They're rare!
@@MichiganRocks I totally understand that. The best rocks are not easy to find anywhere. I do think the Great Lakes have quite a variety of different rocks which makes it fun to look for them. Even if I don't find any rocks it's still great getting outdoors.
@@wyomingadventures What's nice about the Great Lakes is that even if you don't find an agate, there are usually a lot of other really pretty rocks to look at.
Craig says 950 million years ago like it’s totally pedantic - so cool!
Casey loves to walk down the beach 8-10 feet in front of me, then walk back and show me all his cool finds. 😂
Ah, so it's a trend.
Rob, did you get a new camera?
The colors of very vivid. More than usual. And the blue of the lake is more blue tha usual..
No, but I got an iPhone last fall and I've been using it for close ups of small rocks. I used it a lot this day. It's a bit of a pain because when I use my phone, I also record with my GoPro because the sound is much better on the GoPro. It's nice to know it's worth the effort.
Absolutely gorgeous shoreline.
If anyone on the lake superior shoreline is looking to score a ton of fossils fast hunt them at night with a UV flashlight, they have a funny low glow to them under 365nm uv lights. They glow almost a rusty color, kinda looks like chirt. I find boatloads of fossils while hunting fluorescent sodalite.
They glow a pale yellow, don't they? That's how Petoskey stones glow and I think other limestone fossils do too.
@@MichiganRocks yellow is a good way to describe the color, I call it rusty, most the fossils I find are in limestone.
The way I can tell if it's a fossil or chirt at night time is by the smoothness, if it looks smooth it's probably chirt, if it looks rough it's probably fossilized limestone.
Thank you so much for sharing your rock tumbling information, I am new to tumbling and your information has really helped, so has the online forum. I have 160lbs of F.S. sitting in my living room waiting for their turn in the tumbler
We were at Gratiot 2 weeks ago. We live in Central Michigan and love our yearly trek to the Keewanau peninsula. We spend about 80% of our time rockhunting and if conditions allow, a lot of time kayaking Lake Superior. Our latest hunts are for Yooperlites, of course, and what we call "ites", since we are not really sure if it is Thompsonite or Prehnite. Funny to hear you guys have the same conversation!!
I'm completely confused about Thomsonite and Prehnite at this point. Throw mesolite and Patricianite into the mix to confuse things more.
@@MichiganRocks No need to get technical. Cool rock will suffice. 🙂
The "thompsonite" thing is the most confusing even for those of us who study geology. x-ray defraction has been done previously on some of MI tech's specimens and much of the data came back as the structure of mesolite or natrolite which are both, along with thompsonite, under the class of minerals called zeolites. Which as a class has nearly 50 naturally occurring variations in atomic structure so that makes them very difficult to properly identify without the lab results to backup their exact structure. About that many varieties again have been produced through synthesis in labs. So as a class there are over 100 different zeolites most of which have really cool real world applications in solving problems. But Thompsonite has always been what that pinky white to yellow with radial spray crystals and concentric color bands in the structure has been called in the keweenaw so we will just stick with it for now. Phrenite(typically green or pink with the inclusion of copper) is also radial spray but lacks the clear and concentric color emplacements of the thompsonite.
@@letsgoracing4849 I'm glad it's not just me. One of the subscribers here was actually involved in that study.
@@jimknarr There's no danger of me getting to technical, but you know that!
👍👍
7:43 yup hema tite! 😊
👍👍👍
I like it when the geologist can't positively identify things. It makes me feel so much better when I find pieces of Idontknowazite.
It's not as easy as many people think. When I first started doing this, I thought every rock had a name. Now I know that many rocks are a little of this and a little of that. Even rocks that can be positively identified often require more than just looking at them.
@@MichiganRocks Spot on!!
do you ever find any of the rocks that glow like they have in Lake Superior?
This is Lake Superior and I have found those several times. I've learned to find them in the daytime, just by how they look in normal light. In fact, I found my first two during the day on this beach just a few days before making this video. Here's a video from that trip. I show the Yooperlites right at the end: ua-cam.com/video/iV_Mquy6BR8/v-deo.html

If you had a choice to hunt this beach or Calumet Waterworks beach, which would you choose and why?
Hmmm... Very good question. I have hunted this beach at least a half dozen times, maybe a little more. I have only hunted Waterworks once. I did better at Calumet this summer, and I think there's a little more variety in the rocks there. My sister likes this beach a lot better and she lives in the area.
I guess I'd pick this one just because it's sort of a tradition for me and I'd guess it might get just a little less traffic, but that's strictly a guess not based on much.
I got to get up there and hunt some Michigan Rocks, how long until it's just too chilly?
Depends on how tough you are. I'd think the lakes would start freezing around late December up there, but I'm not sure. I have hunted in late December in Lake Huron.
@@MichiganRocks NM tough! great to know!
Around 6:14 to 6:36 there are bluish-green (iridescent ?) splotches in the bedrock on the left side of the image. These are not reflections from the water itself because the water on top is constantly splashing around. It seems to be some kind of reflective mineral or organic material embedded in or on top of the bedrock, and the appearance of the color reflection varies with the camera movement. I'm curious what it could be.
I see what you mean, but I don't know. My guess is algae, but it's hard to tell from a video and I don't remember from when I was there.
@@MichiganRocks OK thanks. Just curious. I think it is reflecting the color of the sky and it might be due to something slimey stuck to the rock. The more I think about it, the less likely I think it is a mineral precipitated within the bedrock.
@@darkwood777 I don't think so either. I think I would have noticed that.
I cringed when you dropped the faux Omar. That one was pretty neat. I know that it wasn’t one that could have been polished.
Sorry, you know me, if I can't make something out of it, I'd rather leave it for someone else who would enjoy it more.

Pardon my naivety but what's the significance of agates? Just very pretty?
Yes, they can be really beautiful. That one tiny one in this video was an example of a pretty one, although most were just bright little chips. I just did a quick little Google search to find some pictures for you. There's a short little slideshow of some really pretty Lake Superior agates on this page: thegemshop.com/pages/gallery-lake-superior-agate
There are many other types of agates too that are also amazing. Here's a rock tumbling tutorial that I did where I tumbled Mexican Crazy Lace agates. Skip to the end and check out the slideshow. I think you'll understand the fascination with agates afterwords: ua-cam.com/video/ksrmpPZrAuU/v-deo.html
Nice finds. And it sounds like y'all had fun.
God bless..
I always have fun when I'm on a beach!
Are all the red stones just clay?
No, a lot of it is probably rhyolite.
1:09 950 million years? I bet if you go back to that same exact spot in one year, that sandstone will have different layers, it will look much different with new elevations. Actually, I don't bet on it, I guarantee it.
It might. Sandstone wears pretty quickly. You might be surprised to find out that I completely believe that God created the earth. I believe that he created it over billions of years, but I might be wrong. Maybe he created it in six days like I'm assuming you believe. Either way, God created the earth and I'm thankful that he did.
Patriciaite?
At 5:10.
Definitely a possibility. I'm confused by Patricianite, prehnite, and thomsonite. From what I understand, patricianite is prehnite with microscopic copper that turns it from green to pink.
When we last went to lake superior we were looking for good green and white rock. GO SPARTANS!
You're lucky that you have a chance of finding your school colors. I taught for 30 years in Alpena where the colors are also green and white, so I think of them as Alpena rocks.
I know people have their own ways of pronouncing certain words and I'm o.k. with that, but many in geology come from specific root words and the one that bothers me when people pronounce "brecciated" as (bretch-ā-ted). The word is related to the word "breach" (n): a fracture, or the act of breaking (the word "break" also etymologically linked to "breach"). So it _should_ be pronounced (breach-ē-ated), since the "cc" in Latin, Italian, etc. is "ch" and the "i" is usually (ē). I'm o.k. with (bree-she-ā-ted), but (bretch-ā-ted) just sounds weird. Lol
I've always heard it with an sh sound in the middle. Craig was the first I have heard pronounce it with a tch sound in the middle. I had no idea that the word came from the word "breach", so that's interesting.
How about prehnite? Is it a long e or a short e sound? I've always gone with a long e, but I hear just as many pronounce it with a short e.
And what about hematite. I used to go with a short e, but switched to a long e because I figured it should sound like hemoglobin.
I suppose I should just start looking some of these words up!
egg
Egg?
Hematite and hematology share the same root word. Ask a blood doctor how it's pronounced. You are saying correct. Lol
Yes, "hemoglobin" is the word that made me decide to start saying it with a long E.
so you guys went northeast up the beach? or was the bigger remote looking area to the west?
We went to the northwest. A few days earlier, I went the other way with my family.
