Carolyn Tewksbury-Christle is a structural geology and tectonics professor in the Geosciences Department. Carolyn completed an undergraduate degree in geology and physics at Smith College and commissioned into the Air Force in 2007. She served as an officer and a research physicist in the Air Force and taught physics at the U.S. Air Force Academy. After 9 years of service, Carolyn separated from the Air Force to pursue her doctorate degree in geology at ETH Zurich, Switzerland. She joined the faculty at Fort Lewis College in 2021 and teaches Physical Geology, Earth Shock, Geologic Field Methods I & II, Structural Geology, and Senior Seminar.
Carolyn’s specialty, structural geology and tectonics, is the study of how rocks bend and break and how that deformation affects the motion of plates on the surface of the Earth. She investigates how rocks deform from the micro- to macro-scale, using a combination of techniques, including field mapping, macro- and microstructural analysis, geochronology, geochemistry, and geophysical analysis. Her primary research focuses on using the rock record in northern California to better understand the processes and hazards of modern subduction zones. She also researches nearly 2-billion-year-old-processes recorded in deformed minerals in the San Juan Mountains and is currently developing virtual field trips for the geology in the Durango area.
