Buried machinery in a barn lot, Dallas, South Dakota, United States, due to Dust Bowl conditions, May 1936. Dust storms from 1930–1939 caused major ecological and agricultural damage to American and Canadian prairie lands. This ecological disaster was a result of drought conditions coupled with decades of extensive farming using techniques that promoted erosion. Photo credit: Sloan, USDA |
