Dust Bowl,1935
Dust Over Texas circa 1935. Huge boiling masses of dust that blocked out the sun were common sights in Texas during the Dust Bowl years. 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 from 1930 to 1936 (in some areas until 1940). 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 ploughing 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
