An excavator accidentally brings to light the logs. The clay has prevented the process of fossilization. Later analysis reveal the affiliation of the species of redwood logs dating back to the Pliocene, dated from 3 to 5 millions years ago. The only case in the world of non-petrified botanical fossil. The necessity is to protect the trees and make the site available. The paleobotanic museum of Fossil Forest provides a cover that is opened in correspondence of the trunks. Inside, an exhibition tells this story, alternating past and present, in a volume ideally suspended between the highest trees in the world.
