Geology Major

Explore Earth’s formation and evolution over time, as well as the interplay of active processes that continue to shape our planet. 

As a geology major or minor, you will study the Earth’s processes in classrooms, labs and in the field.

The department offers five major tracks: General Geology; Environmental Earth Science; Earth, Planetary and Space Science; Geochemistry; and Public Policy

Our location is perfect for field exploration and research with trips to spectacular settings ranging from the Mojave Desert and remote Utah to our nearby mountains and desert.

Michael Wucher '17

Physical Modeling to Investigate Surface Deformation on Venus

Michael Wucher ’17 was part of a team using map-derived hoop strain and elastic models of reservoir inflation to quantify dike displacement on Venus.

Faculty & Teaching

Our faculty studies Earth's geologic processes in the field and lab. Their expertise includes sedimentology, paleontology, rock deformation, magma formation and fluid flow, volcanic eruptions and planetary geology. Their research is supported by NASA, the National Geographic Society, the National Science Foundation, the Research Corporation and Sigma Xi.

Professor Jade Star Lackey

The very location of the College, at the edge of two tectonic plates, means that the Department is fortunate to be able to offer students an education in one of the most geologically diverse and active places on the planet. Our major's field, classroom and research experiences are among the best and most complete in the geosciences.
