Among many great national achievements during the Great Depression, the Grand Coulee Dam remains one of the most impressive. This fine website from the American Experience program complements a documentary that was first aired on PBS in 2012. The construction of this dam would, in the worlds of President Franklin Roosevelt, be part of a "planned promised land" that would transform the lives of farm families. The site includes a great interactive timeline, a photo gallery, and a short preview of the entire film. Additionally, the site includes two nice bonus videos, including one that deals with the processes of closing the spillway. The blog on the site includes several interesting posts on the history of the dam. Also, visitors have the opportunity to share their own stories about their own favorite iconic structures in the United States.
