On April 14, 1935, the “Black Sunday Storm”, the worst dust storm of the U.S. Dust Bowl — an ecological and human disaster caused by misuse of land and years of sustained drought — occurred. Immense dust storms—such as the “Black Sunday Storm” —often reduced visibility to a few feet, as can be seen on the photograph below, courtesy of Dorothea Lange Collection 1919-1965.
Another photograph from the same digital collection shows the tenant farmers displaced by the Dust Bowl in Texas.
