Renaming of Main Interior Building

In 2010, the United States Congress passed legislation designating the Main Interior Building in Washington as the " Stewart Lee Udall Department of the Interior Building.", in honor of his contributions. The bill was signed into law on 8 June 2010. Stewart Udall served as Secretary of the Interior for eight years (1961–1969). Stewart Udall died in March, 2010 at the age of 90.

The project was halted in 1942 due to the US entrance into World War II. At that time, Adams had made more than 200 images during a trek that began in Yosemite National Park. He photographed more than just nature, portraying Boulder Dam, at the time the world's largest. A special part of Adams’ assignment was to show Natives American life and culture.
