In 1941 the National Park Service commissioned noted photographer Ansel Adams to create a photo mural for the Department of the Interior Building in Washington, DC. The theme was to be nature as exemplified and protected in the U.S. National Parks. The project was halted because of World War II and never resumed.

The holdings of the National Archives Still Picture Branch include 226 photographs taken for this project, most of them signed and captioned by Adams. Almost all are in the public domain. https://www.archives.gov/research/ansel-adams/
