Geology majors take courses such as introductory calculus, chemistry, and physics, or biology, and are encouraged to take at least one introductory course in a foreign language and one in computer applications. Subsequent geology courses emphasize the various fields of study within the discipline. Field geology teaches techniques used in field mapping, and one also learns to use a pocket transit and other surveying instruments. Upper-level courses include the study of geologic maps, earth structures, and the rock and fossil record.
Many courses have field trips which last from one to four days.
The required six-week summer field camp in South Dakota is considered by most students to be the unifying highlight of their studies. Knowledge from the classroom is put into actual practice here. Students may also select classes from a broad range of electives. Some emphasize environmental concerns, water resources, and mineral and energy deposits, while other courses involve the earth's history and the engineering applications of geology. Students may wish to study geology of landforms through elective courses such as glacial geology and geomorphology.
