Each summer students travel to The Black Hills of South Dakota for an unrivaled opportunity for geologic studies. Students examine a wide variety of rocks, geologic structures, geomorphic features, and mineral deposits. Geologic mapping and interpretation is strongly emphasized and the instruction includes field and surveying techniques, and mapping on aerial photographs and topographic base maps. Some field exercises take place in the Powder River Basin and Big Horn Mountains of Wyoming, and Yellowstone and Grand Teton National Parks.
