How Did James Hutton Discover The Rock Cycle? Finding sea shells in rocks on high ground spurred Hutton to investigate rocks ever more deeply. Image by Centpacrr. He started making discoveries about rocks, and although he was not first to make these, he made them independently. He noticed many rocks seemed to have started as
