The Dust Bowl was a period of severe dust storms causing major ecological and agricultural damage to prairie lands in the 1930s. The phenomenon was caused by severe drought combined with farming methods that did not include crop rotation or other techniques such as soil terracing and wind-breaking trees to prevent wind erosion. During the drought of the 1930s, without natural anchors to keep the soil in place, it dried, turned to dust, and blew away with the prevailing winds. At times, the clouds blackened the sky, reaching all the way to East Coast cities such as New York and Washington, D.C. Millions of acres of farmland were damaged, and hundreds of thousands of people were forced to leave their homes; many of these families migrated to California and other states, where they found economic conditions little better during the Great Depression than those they had left. Filmmaker Ken Burns has produced a new documentary on the Dust Bowl airing on PBS stations this month. (...) Source: Plog Photo Blog
