University Street was a river of green Monday morning when the University of Oregon class of 2013 began the march from the Erb Memorial Union to Matthew Knight Arena for commencement. Several smaller commencement ceremonies already took place on Sunday afternoon with more throughout the day on Monday. The Emerald will be tweeting and writing from the frontlines today.
