St. Leon Indiana Questions!


jwestbury

Recommended Posts

When you took your trip to st. Leon, we’re you nervous? I read that Indiana is lame and doesn’t allow collecting on their road cuts. I plan on making the 3-3.5 hour drive there but I’m so nervous I’m going to get in trouble and I don’t know where to park lol. I’ve read recent posts of people going in the past 6 months, and no complaints or issues. Or are there any sites to find trilobites in that area? It’s not a short drive lol

St. Leon as far as I know is fine to hunt at.

Pull off the shoulder - there should be plenty of room to park. Just be careful on the exposed ledges. 

Have fun, and be prepared to crawl along to find the trilobites there.

Yep, I collect there often as do many others. Just don't dig, surface collecting only.

Thank you!

I agree. No issues for me when hunting there. I’ve been a few times.

 

I know that others besides me and Connor, like @Nimravis and @Jeffrey P, hunt there as well.  I haven’t heard them mention any problems. Since I tagged them, they can chime in and correct me if I am wrong. ;)

I have never had a problem at the many sites I collect in Southern Indiana- St. Leon, Brookville, Lawrenceburg, etc. in fact, I’ve had a couple of police officers stop and get out of the car and talk to me about fossils, and how they used to collect on the roadways.

Like Wayne and the others, I've been to St. Leon a few times. I've never had any issues there with police or anybody. It is truly a great Ordovician site. However, last time I was there I didn't see any trilobites. This may have been because of the long drought last summer and fall, but the trilobite collecting there is far better after a good rain. Best of luck.

Thank you everyone! I had a pretty good haul!!! Spent the day out there :) does anyone have any good tips on washing them? Do you prefer dry? Just with a brush? What about any rusted stuff? Do you use citric oxide? What about algae? Do you prefer water? Soap and water?  Thank you! Jessica

There used to be (still?). a big sign about "No Digging". Apparently many moons ago someone did some serious digging.  Just show common sense when there. Pull your vehicle well off the road, don't liter, and don't knock rocks down into the drainage or into the road.

Congrats on making the trip down there and the good haul!


I have only ever used water and a tooth brush, or possibly a stiffer nylon brush. I’ve let some of the dirtier ones soak for 5-10 minutes in warm water, but that is about it. 
 

Oh, and…. I agree with @Fossildude19Pics, or it didn’t happen! :TongueOut:

And my biggest cephalopod find. Would be pretty cool to find a large mostly intact one lol. And another death plate. Have a few more and some more death plates to go thru. But this is the just of it :)

Dude I love St. Leon if it was a person I would marry it! That is an excellent external trilobite mould. You did good, there's alot of ground to cover for one person.

It does not appear to be a mold, but rather a flexi in ventral view.

There's a layer in the Liberty below the minuens butter shale that can produce larger F. retrorsa. It is covered by talus at this site but occasionally specimens find their way out. Possibly where this specimen came from.
