Effect of glacial stream from Spencer Glacier
About the collection
Cornell professor Ralph Stockman Tarr (1864-1912) and his students and collaborators organized several expeditions to glaciated areas in Greenland and Alaska. We are in the process of digitizing approximately 2,000 photographs from these expeditions. Because glaciers are a dynamic landform, especially given current climate change, it is interesting to compare these historic photographs with more recent ones to document their changes over time.
