Hi, Jordan.
Please read another two suggestions:
- Use our locality database and don't write it directly. More information: New Data Base of localities within the FMF! . It is really a powerful utility.
- If you are posting many pictures at the same time please don't write a new post for each one, but put them together in a single post. You can attach up to 15 pictures. More information: How to add multiple photos to a Post .
Thank you.

Calcite in Quartz geode. This specimen was one geode with both halves pictured. I was super relieved that I didn't damage the calcite growths, since they were growing into each other!!! Patience is definitely key in cracking geodes with a hammer and chisel.

Hi Jordan. Is this place where you dig open to public or is it a private place? How about sharing your adventures in a separate thread?

The place I go is a roadcut in the next county over but only 10 minutes from my house. It's public and I've been wearing it out since about August. I was actually late to the show in a way, from what I've heard when they first were doing construction you didn't even have to dig. The county just left huge boulders on the side of the road and people took them by the truckloads literally. I have really enjoyed it and I've gotten a lot of experience mining minerals. The majority of what I get comes out of geodes or vugs. I'm a big fan of the cubic calcite, but have yet to come across any fluorite. I'm keeping my fingers crossed. Here are some photos of me and my son's working it. They're 5 and 8.

That is fantastic and so close to your house! I like the fact that the youngsters join you; start them young:-)

Believe me I'm a very blessed man to be able to teach and share in the experience I'm like you start them early 👍👍

I have been contacted by someone who has challenged the identification of copper in these geodes. He states that copper has not been found in them and he believes that the brown film is probably an iron oxide alteration of pyrite.

I agree, we will wait for a while and then fix it...

Jordan, I must laud you for getting youngsters interested in rock collecting, but at the same time, I must admonish you for not demanding that the youngsters wear hard hats while collecting at that roadcut. It is not the large rock that falls and squashes anyone collecting at roadcuts, it is the small pebble sized stone that falls and puts a gash in the head requiring an ER visit with stitches in the head.

Jordan,
Now that I am registered, please permit me to give you a primer on what you are finding.
You are finding Mississippian age sedimentary geodes. They have nothing to do with igneous types. Certain layers of geode bearing Mississippian age limestones come to the surface (roadcuts) or near surface (quarries) in north central Tennessee as in your Woodbury roadcut, central Kentucky, as in the Hall's Gap roadcut.....famous for its millerite, and south central Indiana as in the Harrodsburg roadcuts south of Bloomington.....famous for many hi quality Indiana geodes. Also there are geode bearing roadcuts and quarries in northern lower Michigan and west central Illinois and, especially, the Keokuk region of SE Iowa, Missouri and Illinois.
The geodes that you are finding are basically quartz with certain well documented secondary minerals. Commonly found are calcite and dolomite; occasionally found are aragonite and Baryte; relatively infrequently found minerals include pyrite and marcasite. Rarely to very rarely found minerals include fluorite, millerite, malachite and chalcopyrite. Several other minerals have been "reported to occur" but reliable reports or pictures are not well documented. Other minerals, including some that you have mentioned (native copper) are not known to occur in Midwest sedimentary origin geodes as these are not from the proper geologic environment. Some roadcuts produce differing % of the above minerals such as the Hall's Gap cut producing many millerite geodes while other cuts rarely produce any millerite. Secondary coatings and iron staining is very common; your examples show the iron staining.
Maps of the Midwest geode producing areas, pictures of the roadcuts, numerous pictures of hi quality geode finds at these roadcuts and quarries, and discussion and descriptions of all this can be found in several sites online. Also several folks have had geode displays at many regional rock and mineral shows. So I urge you to take some time and review these. Some of the finds and displays are quite incredible. CHEERS.......BOB

Thank you for the information and the reply Bob I really appreciate it and value any amount of knowledge I can gain. I've really enjoyed working that roadcut I'm currently locating quarries nearby that have been abandoned and I'm going to hopefully be able to recover some specimens willing I am able to acquire the right permission to do so. I have also located an abandoned mine but I'm a little nervous to try that route but with time and experience maybe I'll be able to recover some quality specimens. In regards to the hard hats I'm currently awaiting an order by mail hopefully they come soon my boys are yearning to have more adventures. Again thank you for all the info I will review to have a better understanding on what I'm finding.
