I don't know how formatting works very well here yet so I might split this up into multiple posts in the thread to keep pics organized.

We took a trip in Eastern/Central KY last week and I'm just getting around to taking stock and pictures of our stuff, work is always getting in the way of the REAL IMPORTANT TASKS .

Our main destination was Mammoth Cave National park but all my favorites were found at a couple of spots along the way. Geodes and fossils were my hope.

We ended up with 2 really nice and big, complete geodes plus many fragments of ones that cracked naturally or were other peoples' trash (But my treasure.) One of the complete geodes we found my bf's mom actually kicked like a soccer ball, joking and me "Yes! That's exactly what we're looking for!" Our rockhounding spots were a little limited by time and accessibility but I think I got some good prospects for next time. 

I was calling these "Overachieving geodes" but I think they'd be considered agate? I've seen pics of Kentucky Agate and they're much prettier than this but that might be confirmation bias, cause who's taking pics of ugly agate. (Me, it's me.)

I'm going to try polishing some of these up just to see what happens. I've got my patented Ten Dollar Polisher™ from Harbor Freight I'm going to start playing with. 

Awesome Field Trip Report, Alina! Thank You!
Sounds like you had a great time, and it sounds like you've got the "Rock Bug" bad, which is a Good thing!
Well done on your first report. The way you figured out to do it is the same way I do it. A little bit of text and a few pictures with each post.

Glad to hear Mammoth Caves is still there! I grew up in Iowa and barely remember our family trip there in the 1960's. Great place to grow up but as Mom would often lament, "It's just so far from 'anything'. 
Anyway, Love all the pretty crystal geodes and I'm glad you already know about Iron Out. You can try soaking hard to clean specimens more than once, 2-3 days at a time with a good rinse and spray inbetween, but sometimes the colors are going to be included in the quartz and just won't come out.
Now those "Geode Overachievers"( ), are a different animal. The first one you have pictured, sliced open, may be an agate, and, because of the little hollow cavity in the middle, is definitely a geode. But all the rest of your samples are a type of Chert Nodule called "Hornstone". Some people call them flint nodules. Very good material for knapping found in Kentucky and Tennessee.

Thank you again for the report!
