On our midseason finale we hear from Dr. Brian Yanites, a geomorphologist looking at how changes on Earth's surface can impact or are impacted by people, weather, animals, and even ore deposits. Learn a little bit about the history of topography, how the geosciences incorporates drones and lasers (and a time when the drones weren't very well received by some folks on the ground), and his time pre-geomorphology as a collegiate athlete playing football.
