In 1971, the newly founded Environmental Protection Agency announced the start of a photodocumentary project. The EPA gave free rein to a nation of free lance photographers in documenting a changing American environment. Documerica was the result, and it ran through 1977.
Of the 22,000 plus photographs submitted, over 15,000 have been digitized and uploaded to flickr. Here are a few of the Alaskan photos taken for the project.
