Field Trip to Flynn Creek Crater

The Flynn Creek impact structure is located less than 20 miles from Tennessee Tech in Jackson County, Tennessee. Students in the Spring 2019 Planetary Geoscience class visited the structure on April 6th for a half-day field trip with Dr. Richard Finch, a Department of Earth Sciences emeritus professor. Geologic stops focused on: (1) deposition of thick sequences of Chattanooga Shale following the impact; (2) deformation along the margins of the crater; (3) deformation around the central uplift in the crater; and (4) styles of impact breccia deposited in the crater. Special thanks to Dr. Finch for his knowledgeable tour of the structure and local land owners for allowing the class to visit outcrops located on private property.
