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.

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'

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.
Mike Streeter

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.

MI rock baby
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
Mike Streeter
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.

My son really loves rocks and I thought it would be fun for him to go hunting for geodes once the weather warmes up and smoothed out in the spring. I've read the thread and it looks like the lake Monroe area is a good place to go, but I was wondering if there was a good area to look. We don't mind walks, but I'd like to be able to find a few so he can bring them home and open them. Any help would be appreciated.
We are looking to go over to indiana and hunt some geodes possibly this coming weekend the first weekend in October 2015, can anyone give me some insight as to were to start?  I was planning to head toward Monroe lake and i also remember reading about a general store that the owner will let you search the creek behind his place.  

We are heading over to Flint Ridge ohio tomorrow and would gladly pick up some flint for a local indiana person and do some trading if they wanted to help us make our weekend geode trip to indiana next weekend productive.   Thanks Jerry
So we were told go to Indiana and collect some geodes around the Lake Monroe area and Bloomington, so I have been researching where to go and asked the DNR if they had any maps or any ideas where we could go, they replied there is no legal rock collecting in Indiana and we can be charged with a crime for stealing state property?  We were just at a show here in Michigan talking to a rockhound who goes to Bloomington area and picks up geodes all the time he said.  Does anyone know if there is actually a place you can go and pick up geodes without getting into trouble or should we just take Indiana off our rockhounding plans?  

Mike Streeter

I would think that the DNR person was referring only to public lands controlled by the state or federal government.  Geodes can be collected on privately held land with permission.  Do a search on this message board for "Indiana Geodes" for specific collecting information and advice.  Remember though, anytime you find yourself in legal doubt about any potential collecting location, walk away.

I suggest that you extend your geode collecting radius to include the Keokuk, Iowa area where fine geodes may be collected without having to fear breaking the laws.  Go to the following web page for more information:

Good luck!

Since no one has posted on this Indiana thread for about 9 months now, I thought I might bring an update to the collecting status here in Indiana. I do not profess this to be 100% complete or absolutely accurate, but I will try.

In general, casual and experienced collectors can collect minerals, fossils, and geodes in a number of locations. These include quarries, stream beds and lake shores, and road cuts.
I will discuss them separately with a few updates.

While there are numerous limestone quarries thru out the state, few if any, are open to individual weekend collectors.   Some are VERY off limits while others have a more "enlightened" attitude toward collecting.  In general the best way for casual collectors to get into a quarry is to hook up with a local rock club that offers field trips to the area quarries. The "enlightened" quarries usually admit clubs on weekend collecting field trips.   A few collectors develop close relationships with quarry management and are allowed in to collect, but the key words here are "few collectors" so if you are game, approach the individual quarry managements in their quarry offices and discuss the possibilities.
One recent closure that I am aware of is the Hoosier Stone Quarry (Salem Quarry) in Salem, Washington County Indiana. This formerly productive quarry for celestite and calcite is now flooded. Many other formerly productive quarries have now been closed for years. I have no other specific info about the status of other quarries.

Stream beds and lake shores have always been productive of fossils and geodes. After a wet spring, it has now turned dry with lower water levels. If you are willing to fight the bugs, poison ivy, and dense pricker bushes a stream bed or lake shore rocky beach might be your best summer bet.   Geodes, which I will discuss next, are only found in South Central Indiana so hiking a shallow stream bed in this area might be productive.  Near and under road bridges is a good way to start and be very aware of private property as some folks are very sensitive to any trespassing.   Several southern Indiana lake shores are productive, but most areas (however not all!!) along Lake Monroe are off limits to collecting.    If you are up for a hike, check where along the lake shore are the open stretches for fossil and geode collecting (with hand tools only). These stretches of lake shore generally are those administered under the auspices of the feds (federal lands away from the dam) and not the state of Indiana. Having a map and asking at the DNR office might be of help.

In Indiana collectible geodes, always a favorite for collectors, are found only in the south central part of the state. They are found only in the counties of Monroe, Brown, Lawrence, Washington, and part of Jackson.  A few other nearby small sites might also occur, but they tend to be very localized, on private lands, and not productive of any really collectible examples. The geodes, along with fossils, can be collected not only as I just mentioned in stream beds and along lake shores, but at road cuts in this part of the state. The 2 best known road cuts are the Harrodsburg road cuts in southern Monroe County and the Rte 56 road cut about 6 miles East of the town of Salem in Washington County.
Best time for collecting at these sites is in late winter thru mid spring after freeze/thaw episodes with rock falls. So the best collecting is now past for this current 2016 season.
If you are energetic, bring heavy tools including a sledge and pry bar otherwise you may only have very limited success. It has been my experience that the local police will leave you alone as long as they see that you are aware of safety. Bring a hard hat, park well off the road, and no young children with a short attention span and wanderlust at the roadside collecting site.   Good luck and hope this helps!     CHEERS.......BOB

Vernon Stallins
Thanks for that info Bob. I was just searching earlier and came across your name and was trying to find you on FB to ask you about possible locations. I will look at those counties and areas on the maps and hopefully with any luck find some nice items to add to my collection this year. Thanks for the info.
