Just twice a month, dinosaur fans have an opportunity to take a hike in this fossil treasure-trove with a paleontologist and see what they can find. It's just a 1-acre site but it's one of the only intact deposits of fossils from the Cretaceous Period on the East Coast. You can't take your finds (if any) with you; they go to the Smithsonian Institution. Stop when the park is closed and see the garden with plants from dinosaur times and informational signs about the fossils and local history.
