American Environmental Photographs, 1891-1936: Images from the University of Chicago Library
http://memory.loc.gov/ammem/collections/ecology/index.html
American Environmental Photographs is an online representation of approximately 4,500 photographs from the University of Chicago Library documenting natural environments, ecologies, and plant communities in the United States at the end of the nineteenth and the beginning of the twentieth century. Among the natural features these images document are ecological settings such as dunes, bogs, forests, and deserts; individual plants from the Ponderosa pine and birch to grasses and mosses; landscape features like the Grand Canyon, Lake Superior, and the Sierra Nevada; and the consequences of natural and human changes to the environment ranging from erosion and floods to irrigation and lumbering. Comparison of early photographs with later views highlights changes resulting from natural alterations of the landscape, disturbances from industry and development, and effective natural resource usage.Search this collection by keyword or browse the photographs by subject or geographic location.
