The most visible evidence of how dry the 1930s became was the dust storm. Tons of topsoil were blown off barren fields and carried in storm clouds for hundreds of miles. Technically, the driest region of the Plains – southeastern Colorado, southwest Kansas and the panhandles of Oklahoma and Texas – became known as the Dust Bowl, and many dust storms started there. But the entire region, and eventually the entire country, was affected.
between 1930 and 1940, severe drought coupled with decades of extensive farming without crop rotation, fallow fields, cover crops or other techniques to prevent erosion, led to major ecological and agricultural damage to American and Canadian prairie lands. Millions of acres of farmland became useless, and hundreds of thousands of people were forced to leave their homes.
