FIELD TRIPS: Jelle Zeilinga de Boer, the Harold T. Stearns Professor of Earth Science, Emeritus, took students enrolled in his Graduate Liberal Studies Program SCIE 641 Earth Resources course to the Old New Gate prison and copper mine in East Granby, Conn. July 12. Here, he points out copper sulfate in the mine ground’s walls.

|De Boer uses a particle detecting instrument to locate uranium in the copper mine. His summer class studied the occurrences, origins, and usages of Earth’s principal mineral and energy resources.|
