In this episode, Noah travels to Arizona to explore two very odd geologic sites, petrified forests laid down beneath thin rock layers on the desert floor, and a large gouge on the sedimentary layers near the Grand Canyon. The first site reflects the catastrophic events during the Flood and its aftermath. The second site, under a hundred miles away, has helped scientists discover catastrophic processes around the world by bombardment of meteors (which are NOT responsible for the extension of the dinosaurs).
