Buried machinery on a farm in South Dakota during the Dust Bowl, 1936.The Dust Bowl was a series of dust storms that caused major ecological damage to the North American plains in the 1930s. The storms were caused by prolonged drought and decades of farming techniques that increased soil degradation. During the drought, soil dried, turned to dust, and blew eastward and southward in large dark clouds. At times, black clouds reached all the way to East Coast cities like New York and Washington, D.C. The Dust Bowl caused the largest migration in American history within a short period of time. By 1940, 2.5 million people had moved out of the Plains states; of those, 200,000 moved to California. -- source link
