Quarry Program: "Aquarium in Stone" What better way to explore a fossil park than with a paleontologist in a fossil quarry. On Fridays and Saturdays during the summer, 11:00am-4:00pm (weather permitting) visitors can participate in the scientific collection of fossils. This is a great opportunity to get your hands dirty and see a fossil revealed after being buried in stone for 52 million years!

We hope you enjoy the hike, the opportunity to see fossils in their original position, and the interaction with our GeoCorp intern stationed there. Wear comfortable hiking boots, sunscreen, and bring drinking water and insect repellent. Inquire at the visitor center for directions.

All fossils remain in the monument's museum collection for scientific study. Allow 1.5 hours for this program.

If you discovered a fossil while participating in this program, go here to view the data collected.
