Overview and Contact Information
The geology major offers students hands-on learning in the classroom, lab, and field. Intermediate and upper-level courses are relatively small and explore geologic materials, physical and biological processes, and earth history and change. We recommend strongly courses in the cognate sciences (biology, chemistry, and physics), as well as calculus and/or statistics.
Learning Goals
Students majoring or minoring in geology learn about the dynamic processes and history that shaped our planet and provide us with the resources and natural environments on which we rely. This is a fascinating field of study that also prepares one for outstanding employment opportunities. Our courses are designed to achieve the following learning goals:
- Develop observational and quantitative skills appropriate for field, laboratory, analytical, and modeling methods of geoscience inquiry.
- Develop sophisticated and nuanced reasoning skills to evaluate multiple working hypotheses, integrate earth science data gathered at different spatial and temporal scales, and critically assess data, ideas, and methods from the published literature.
- Become an effective communicator, able to ask interesting questions, collaborate with peers, and engage thoughtfully and respectfully in discussion; to write about scientific observations and interpretations using appropriate vocabulary and style; and to orally and graphically present data, ideas, and methods from your own research and from published literature.
- We encourage geology majors to be informed about ideas and methods within the cognate sciences of biology, chemistry, physics, and math and statistics.
- Geology majors will understand the importance of earth processes and materials in shaping the history and future of humanity.

Course Offerings
GEOL-104 Introduction to Geology and Physical Geography
Introduction to Geology and Physical Geography courses are designed to serve first-year students and sophomores interested in exploring the natural sciences. These courses also prepare students for upper-level coursework in geology, physical geography, and the earth, oceanographic, and atmospheric sciences. Students may only take one section of GEOL-104.
GEOL-104AP Introduction to Geology and Physical Geography: 'Art in Paleontology'
Fall. Credits: 4
Paleontological art brings ancient organisms back to life. In this course we will consider the role that PaleoArt itself plays as a mode of scientific discovery. Beginning with an analysis of the pioneering paleoart of Charles R. Knight, we will examine how paleoartists have uncovered key information about prehistoric life well in advance of its recognition by the scientific community. In a collaborative class project, we will identify the best and most representative of "paleort". For individual final class projects, students may choose between a research paper and presentation, and their own paleontological artwork in any visual medium.
