The Dust Bowl, or the Dirty Thirties, was a period of severe dust storms causing major ecological and agricultural damage to American and Canadian prairie lands in the 1930s, particularly in 1934 and 1936. The phenomenon was caused by severe drought coupled with decades of extensive farming without crop rotation, fallow fields, cover crops or other techniques to prevent wind erosion. Deep plowing of the virgin topsoil of the Great Plains had displaced the natural deep-rooted grasses that normally kept the soil in place and trapped moisture even during periods of drought and high winds.

During the drought of the 1930s, without natural anchors to keep the soil in place, it dried, turned to dust, and blew away eastward and southward in large dark clouds. At times, the clouds blackened the sky, reaching all the way to East Coast cities such as New York and Washington, D.C. Much of the soil ended up deposited in the Atlantic Ocean, carried by prevailing winds, which were in part created by the dry and bare soil conditions. These immense dust storms—given names such as "black blizzards" and "black rollers"—often reduced visibility to a few feet (around a meter). The Dust Bowl affected 100,000,000 acres (400,000 km²), centered on the panhandles of Texas and Oklahoma, and adjacent parts of New Mexico, Colorado, and Kansas.

He is the older brother of actor Jerry Van Dyke, who is best known for his role on the TV series Coach. His grandson, Shane Van Dyke, is also an actor, and directed Titanic II.

Kenneth Lauren "Ken" Burns (born July 29, 1953) is an American director and producer of documentary films, known for his style of using archival footage and photographs. Among his productions are The Civil War (1990), Baseball (1994), Jazz (2001), The War (2007), The National Parks: America's Best Idea (2009) and Prohibition (2011).

Burns' documentaries have been nominated for two Academy Awards, and have won Emmy Awards, among other honors.

Ken Burns was born in 1953 in Brooklyn, New York City, New York, according to his official website, though some sources give Ann Arbor, Michigan, and some, including The New York Times, give both Brooklyn and Ann Arbor. The son of Lyla Smith (née Tupper) Burns, a biotechnician, and Robert Kyle Burns, at the time a graduate student in cultural anthropology at Columbia University, in Manhattan. Ken Burns' brother is the documentary filmmaker Ric Burns.

Burns' academic family moved frequently, and lived in Saint-Véran, France; Newark, Delaware; and Ann Arbor, where his father taught at the University of Michigan. Burns' mother was diagnosed with breast cancer when Burns was 3, and died when he was 11, a circumstance that he said helped shape his career; he credited his father-in-law, a psychologist, with a signal insight: "He told me that my whole work was an attempt to make people long gone come back alive.". Well-read as a child, he absorbed the family encyclopedia, preferring history to fiction. Upon receiving an 8 mm film movie camera for his 17th birthday, he shot a documentary about an Ann Arbor factory. Turning down reduced tuition at the University of Michigan, he attended the new Hampshire College, an alternative school in Amherst, Massachusetts with narrative evaluations rather than letter grades and self-directed academic concentrations instead of traditional majors. He worked in a record store to pay his tuition.
