Ben and Jodie are exploring a canyon, and narrowly escape being swept away in a flash flood. The next day, they return to the canyon to retrieve Jodie's school backpack, and discover some fossilised bones. These give Jodie an idea for her science project and on returning to the site, they meet some palaeontologists who are very interested in their discovery.
