Ancient Pollen, Dinosaur Tracks, Volcanic Ash Beds: Clues to the Past for Geophysicists Superheroes of Science

Ken Ridgway tells us that in order to understand how the world works, we have to be able to study sedimentary rocks, and looking at an active area now helps us see what might have happened in the past. He sets up camp in active earthquake areas of Alaska and intensively researches the sedimentary rocks to discover clues to the past and make connections to today’s world. Ken Ridgway is a researcher and Professor of Geology and Geophysics in the Department of Earth, Atmospheric, and Planetary Sciences at Purdue University.
