Legendary film maker Ken Burns has created lush documentaries about a wide variety of very American subjects, such as the Civil War, baseball and jazz. 

One of his most popular series was "The National Parks: America's Best Idea". Now his latest documentary focuses on just one of those parks, right here in California.

"Yosemite: A Gathering of Spirit" is sponsored by the Yosemite Conservancy and debuts this Sunday in Hollywood.

Ken Burns joins the show to talk about his latest project and his love of California's most famous National Park.
