Requirements for a Major:
A minimum of 42 credits in geology selected from the following courses: one introductory geology course (110 or 120), 210, 220, 230, 240, 250, 255, 258, 260, 265, 270, 310, 330, 350, 365, 370, 375 or 380. Each student must complete 6 credits of Geology 400, Integrative Exercise. Each student must also take the following courses: Physics 112 or two of the three following courses: Physics 113, 114 and 115; Chemistry 123, or 128 (and Chemistry 122 if needed as a prerequisite to 123 or 128); and Mathematics 111 and one of the following: Mathematics 121, 215 or Computer Science 117. Prospective geology majors should take most of the 200-level courses. Students should take three or four 200-level courses before taking advanced (300-level) courses. Participation in a recognized summer field camp is highly recommended for all majors. The basic requirements for the major are considered to be minimal. Students planning a career in geology or the earth sciences should take several additional courses in mathematics and other sciences as well as geology. Students interested in earth science education should discuss their plans with Mr. Buchwald because a number of specific courses must be taken for teacher certification.
Junior and senior majors in other natural sciences may enroll in geology courses numbered 200 and above without the introductory geology prerequisite with permission of the instructor.

Also of interest are the transformation of these sediments into rock and the analysis and correlation of strata. Weekly laboratories and several day-trips (scheduled for weekends) are required. The distance to some outcrops necessitates a late return to campus; participants should note the extended laboratory times for this class. Please consider that both Paleobiology and Geomorphology prepare students for work in Sedimentology, but neither is a prerequisite. 6 credits cr., MS, Fall—C. Cowan
