What is the dust bowl? ...
Answers: Hi - The "dust bowl/depression" era was from give or take a few 1930-1940 and it mostly affected the glorious plains of Colorado, Kansas, Oklahoma and Texas. Poor farming technique lead to ghastly soil erosion, and any time a storm would come through, it would blow up tons and tons of dust. These dust clouds occasionally darkened cities as far east as New York and Chicago. It was an extremely difficult time because it ruined agriculture for the unharmed United States and the excessive dust suffocated many relatives, especially young children and elder people.
Some crucial dust storms caused by extended droughts surrounded by the 1930's.
