Thanks to the U.S. Geological Survey's Astrogeology Science Center, Lowell Observatory, NAU, and the plethora of analog geologic environments in northern Arizona, Flagstaff remains the epicenter of astrogeology research. Take advantage of Flagstaff's rich astrogeologic history by combining the related fields of astronomy and geology.  This minor provides students interested in planetary geology and surface processes with the foundational knowledge rooted in traditional geologic principles. Similarly, students will also gain invaluable astronomical perspectives, building the perspectives of scale and geologic/astronomic time that are necessary to appreciate astronomical context. This minor requires completion of at least 23 credit hours in AST and GLG courses.
