- Environment, Natural ~ Photographs ~ 1891-1936
The collection consists of 4,500 photographs documenting natural environments, ecologies, and plant communities in the United States at the end of the nineteenth and the beginning of the twentieth century. Produced between 1891 and 1936, these photographs provide an overview of important representative natural landscapes across the nation. They demonstrate the character of a wide range of American topography, its forestation, aridity, shifting coastal dune complexes, and watercourses. 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.
