Introduction
Session Three is a condensed, three-week geology field course in the Black Hills of South Dakota and Wyoming. Students examine Precambrian metamorphic, Phanerozoic sedimentary, and Tertiary igneous rocks through accelerated mapping projects. The curriculum covers measuring and describing stratigraphic sections, constructing geologic maps, and drawing structural cross sections.
Lodging is in a dormitory setting, two students per room. No camping is required. The course is limited to 20 students to ensure individual attention.
Projects
- Measure, describe, and correlate stratigraphic sections
- Construct geologic maps of selected areas
- Draw and interpret structural cross sections
