The Corral Hollow field trip is started by Sam McGinnis, a grad student of Stebbins at the time, in the early 1960s. In the early days, different groups of students go out from Tuesday to Saturday night, but with shrinking class sizes, the number of trips drops down to two, on Friday and Saturday. This field trip serves as the capstone for the class and is regarded as the highlight by many students.
