A field trip in east-central Pennsylvania to the Whaleback, a massive formation resembling a sperm whale that was created by pressure forcing layered rock to arch upward, was a highlight of the 2012 GeoGrad Reunion April 30–May 4. About 100 graduate alumni and family members attended the event, which was sponsored by the geosciences department and the graduate school and included a daylong conference on campus. The graduate school is working with other departments to sponsor campus reunions for their grad alumni; Dean William Russel said that the politics and psychology departments are planning events in the coming year.
