At ºÚÁÏÍø, geology majors participate in class field trips and have the opportunity to be involved in an extended summer field excursion. Â In the past few years, we have visited Yellowstone National Park, the Grand Canyon, Crater Lake, and Big Bend. Â These trips provide students with important hands-on learning experiences and opportunity to observe in person world-renowned geologic sites. Â Finally, students incur minimal expense associated with these trips.
