The Big Blue Rock Pod
Welcome to the Big Blue Rock Pod, produced by the Kentucky Geological Survey, at the University of Kentucky. This podcast is a fun, conversational approach to discussing all things geology and earth processes. We primarily focus on Kentucky. We talk emerging ideas in research, along with classic topics in earth science for all levels of interest.
