Carol van Strum of Tidewater, Oregon, has lived inside her document collection for decades. Her documents, many of which were also kept out in the barn guarded by a family of owls, relate to herbicides, pesticides, PCBs, dioxins and many other compounds. Now these and related collections are in digital format and are available as The Gemstone File. Photo by Risa Scott. (PRNewsfoto/Chiron Return)
