Renowned documentary filmmaker Ken Burns chronicles the daily struggles of those affected by the "Dirty Thirties," when horrific dust storms born of a decade-long drought and short-sighted farming methods plagued America's breadbasket during the 1930s. Both episodes of the two-part program─"The Great Plow Up" and "Reaping the Whirlwind"─focus on the stories of Depression-era families threatened by the historic ecological disaster. 4 hrs. total on two discs. Widescreen; Soundtracks: English Dolby Digital 5.1, DVS; Subtitles: Spanish.
