38th Fall Field Frolic: A Frolic of Ice and Fire! (Photos)

The Fall Field Frolic this year was camped at June Lake, CA, with stops at the Owens River Gorge to see the Bishop Tuff, Convict Lake to see the moraines and examine the complex glacial history of the eastern Sierra Nevada, Panum Crater to climb into a volcano, and Bennettveille/Saddlebag Lake to get a close-up view of Paleozoic continental margin rocks that the Sierra Nevada batholith intruded into! Led by Dick Heermance and John Wiesenfeld with special expertise provided by Emeritus Professor and creator of the Field Frolic tradition: Dr. George Dunne! Thank you to all students, staff, faculty, alumni, and friends who attended and made it such a fun trip.
