This is a good distance away from Dayton but it’s well worth the trip.

Oakes Quarry Park

Oakes Quarry Park is a 25-minute drive from Dayton, Ohio.

This site was surface-mined in the 1920s because of its natural limestone.

Today, it’s a beautiful park full of trails, birding and areas where rock is still exposed from the previous mining operations here.

The natural rocky areas are stunning and they still have some treasures to yield. 

Around 440 million years ago, this was a shallow sea.

Fossils dating to this period have been discovered by researchers.

This is still a great place to look for rocks and fossils and there may still be some pretty big finds just waiting here.

There are brachiopods, crinoids and Silurian age marine fossils here.

That’s millions of years of history just sitting on the ground.

There may still be fossils waiting to be found all around this area.
