The Big Blue RockPod discusses the complexity and intrigue of southern Appalachian geology, covering everything from physiography, tectonics, mountain building, age, cool rocks…just don’t say the "T" word! What's the "T" word? Listen to our conversation with University of Kentucky professor Dr. Ryan Thigpen (Earth and Environmental Studies, Structure and Geodynamics Group) to find out!

In this episode, we talk with Jason Dortch, a geologist and geomorphologist here at KGS, about glaciers and glacial processes. While continental-scale glaciers did not cover all of Kentucky, they caused major impacts to the landscape in northern Kentucky and the greater Cincinnati area and beyond. Listen to our conversation with Jason and learn about all things glaciers (and glacier adjacent activity) in Kentucky (or as much as we can fit in under an hour)!

Listen in as we talk with Matt Massey, a KGS field geologist and rock climber, about the geology of the Red River Gorge in eastern Kentucky. There’s a unique intersection between fascinating geology, spectacular landscape, and culture that makes "The Red" world famous.

Welcome to the Big Blue RockPod, sponsored 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, primarily focused on Kentucky. We talk about the past, present, and exciting future of earth science for all levels of interest.
