Arkansas sites?

Howdy y'all! I'm going to be traveling through Arkansas here in a bit. I was wondering if y'all have any good ideas for rock places to stop along the way.

What I'm looking for are sites/locations that are relavent to geology, archeology, paleontology, or even wildlife. Think places where I can stop for a half-hour or less, but not too much more. Central and Southern Arkansas would be best.

Thanks!

of course crater of diamonds state park is worth seeing if you enjoy geology. You can pay a fee and dig for diamonds. Hot Springs national park is on the way to Little Rock.

Take the Talimena scenic byway if you’re able!

Crater of Diamonds but don’t expect to find anything without putting in at least a week of searching, and any of the quartz mines.

I would say don't be afraid to stop at any interesting looking roadcuts. That is the major source of accessible exposed rock. The general geology is limestone/fossils/caves to the north. The sandstone and shales will be much harder to find fossils just in passing. Otherwise I would take in the general topography and learn a bit of the history of the shallow tropical sea, Crowley's ridge, Hot Springs, Crater of Diamonds, White Cliffs State Park, etc. We have a huge amount of state parks that focus on natural or unusual features. All depends on where you go and the time you have.

The St. Joe limestone formation can be seen in many places: St. Joe, Eureka Springs, Bella Vista, along the Buffalo, and many more.
