First off I have to apologize for the pictures...1. they are not the best quality and 2. they are not the best samples we pulled. They aren't the best because my brother and I have routinely gone through our samples and  taken them into our mothers 1st and 2nd grade classrooms and given them away during their "geology week". We enjoy giving them to the kids they get a kick out of it!

All of these are about 6-6.6 inches across except the one with the red outline that one is only 3. If I get the chance to go back ill make sure to keep some of the better ones for you guys!

Were pretty sure they're all quartz...except for the blueish one...we have no idea what that is.

And carly..we honestly didn't expect to find much, we kinda went on a hunch and got spoiled so we only brought one backpack and thank god for that! We ended up getting lost after hiking for about an hour...then for about the next 2 hours we were trying to find our way back, with the help of our phones (and google maps) we ended up hiking about 7-8ish miles total for the day. Most of the better samples we ended up carrying in our hands because they were getting beat up in our backpack.

It was definitely worth the trip though, great outdoors, great weather and awesome rocks.
And a hellofa learning experience.

Alexander,

Your bluish geode is boytroidal chalcedony.  It is sometimes called an agate geode, but is not true agate.  It is more in the jasper family than agate.  These are fairly common in the KY, IN, IL area.

Hello Alexander,

As Harry noted, the bluish, rounded material is chalcedony. Pronounce the ch as a k. Chalcedony is a form of silica, SiO2, just as quartz is SiO2. The difference is that chalcedony has a crystalline structure so fine as to be nearly undiscernable even under powerful magnification. So, just go with very fine crystalline texture. That makes it easier and still correct for the kids.

Speaking of the kids, thanks for your support of your mother's kids. The kids at that age just love this stuff and it's a good time for some hands on geology and science!

And keep beating the bushes. You never know what you will find working off the beaten path. You just might discover that new hot spot with really great geodes. And if the geodes are of a rather common quality but a little bigger, so be it. The kids will love them, especially big just because it's BIG!

I still have the first geode I found almost 50 years ago. That "common" geode I actually found myself, along with some other nondescript minerals got me started as a rockhound and then on to becoming a geologist. I still rather prize that thing as my first trophy find. And I still view myself as a rockhound first who just grew up to be a big kid rockhound with some papers that say I'm an "IST".

Best Regards,
Al O

PS: An IST is a title jokingly started here on McRocks for anyone with a piece of paper saying they have a degree. I love it as it reminds me of how it all began, a couple of rocks and a desire to know more.

Hi -
I live in the NW Indiana area - My friend and I are looking to do some hunting! Never have before, but have always wanted to. 
Thinking about traveling down south one day. See what we can find.
Sounds like an awesome adventure. Any good spots in NWI that anyone knows of? Or would like to join up and hunt?
Lemme know!

Hello rockhounders! I am new to this site, & new to the realm of collecting geodes. After I turned 40, I decided I wanted to do some things I've always wanted to...hunting geodes was one.

I live in southwestern IN & am looking for nearby places to hunt geodes that is not on private property. After reading comments on this thread, we decided to try out a few of the spots mentioned. Our first trip to Ramp Creek, near Smithville, IN. It was more fun than imagined. The return trip was fun for about an hour, then we were unwelcomed. Apparently we were on private property. :-( We were up creek from the original site due to flooding.

We also visited Lake Monroe near the dam & found a few. I'm wondering if we aren't in the wrong location there because so many have said how easy & plentiful they are to find. ??? Can someone give exacts on where to find them?

Any suggestions are welcomed! Geode hunting is in our blood now. It's a family activity we all enjoy! Happy hunting to all'

Melanie, 

give me a shout off line by email and I can give you a site that you can go to and pick up as many geodes that you want to take home out of a creek, near Heltonville. it`s privately owned but the owner is very nice and all you have to do is call and ask him for permission, he owns quite a few miles of the creek there so you shouldnt have any problems. several of my rockhunting friends have been there with no problem at all.

Was a rockhound when I was young. Now that I'm slowing down from some more active hobbies I'm looking to get back into rock collecting again.

I live in Indy and am looking for good locations to get started again.

Can anyone point me in the right direction.

One of my favorite pieces...Bear Creek, Indiana.  Geode with olive green botryoidal chalcedony

I`m sad to report that things have gotten worse at the location in Indiana near Heltonville that I had recommended to Melanie above......I updated a young mother this morning on the situation at that location...she wanted some place to take her seven year old son to look for geodes today on a mother/son trip before school starts in their area and he had the geode fever, so I provided her with the landowner`s contact info. She contacted him and " begrudgingly gave her the general location of the creek access site, but no specifics and wouldnt even give her the creek name so she would have an idea if she was in the right area or not...she asked him how she would know if she was on his property or someone else`s property, not wanting to trespass of course, and he had no answer for her . "  Luckily she was able to drive into the area and find a place where the creek washes up near the roadway and spent a joyful five minutes with her son, picking up geodes and they had a blast, I`m happy to report. 

At any rate, I don`t see this location getting any better, anytime soon. I can only imagine that the calls from clubs are continuing and possibly even someone has damaged his property there, as another of my contacts had hinted to me a few weeks ago when I pressed him for more information about his experience in contacting the landowner about six weeks back. I sincerely hope this isn`t the case, but have seen the respect toward the property of others by rockhounds in the past five years take a nosedive. It`s no wonder many of us cannot access sites we used to any longer.

I happen to live in Brown Count (30 years ) in the heart of geode country . These days, On any given weekend of the summer, i will find at least one person on my posted property, digging out the creek banks for geodes with shovels,, hauling creek rock by the truckloads, even taking limestone spalls that the county uses to stabilize the road/ creek . Noone has ever asked for permission, and every single one said,"I didn'know that this belonged to anyone!".Charlie cole

An explation is in order: I have opened up my oroperty up to ad many as fifty kids at once. Some of them have never before waded a shaded Indiana creek on a perfect summer afternoon. My now adult children and I for years have done geode shows for kids featuring songs and stories about geodes, we crack and share them. We teach environmental ethics in the process. We will be unable to continue this effort if greedy thieves continue to steal as much as they can carry from our property. They really are ruining it for everyone, and deserve to be arrested.

Charlie,

Enforcement is the key to reducing trespassing.  Since trespassing is a crime, by all means contact local law enforcement if there are trespassers on your property.  If the trespassers are caught illegally collecting geodes, they can be prosecuted on theft charges.  When it becomes known that trespassers will likely be prosecuted, your problems should wane.  You may also want to consider granting written permission to a few trusted individuals to collect on your property so they can help keep an eye on it for you and let others know about the conditions for access.

I am hoping someone on this site can help identify a rock that I have found. This rock was found on Lake Michigan in Leland, MI. The exterior has the appearance of a Charlevoix rock/fossil, The second interior layer is cornflower blue similar to that of a Leland Blue (slag which was a byproduct of steel smelting in the 1860s) there is a pea size hole on one end I took my husbands loop and inside our mountains of clear crystals similar of images I've seen of geodes. I have also taken a red laser light and shined it in the hole and it is opaque in some areas and translucent in others. But again the entire exterior is definitely the appearance of a Charlevoix on top and fossil striations markings on the bottom. I

Sounds like a bluish-colored chalcedony concretion lined with quartz crystals within a limestone matrix.  I have found similar rocks near Charlevoix, although very few and far between.
