Biographical / Historical:
In January 1930, at the urging of Senator Carl Hayden, the Smithsonian arranged with the Department of War for air reconnaissance of ancient canals in Arizona. Because the canals were being destroyed by the extension of agriculture and other developments, oblique and vertical aerial photographic records were made of them. Neil Merton Judd represented the Smithsonian on the project.
The digitization of this collection was supported by the Pueblo Grande Museum.
