"Black Sunday" refers to April 14, 1935, a day marked by a severe dust storm that devastated parts of the United States, particularly the Great Plains. This event was a significant consequence of the Dust Bowl, a period of severe drought and poor agricultural practices that led to massive soil erosion. The storm created dark skies and reduced visibility, affecting the health and livelihoods of many families. The storm was so intense that it became a symbol of the environmental and economic challenges faced during the Great Depression. It prompted changes in farming techniques and government policies aimed at soil conservation, leading to initiatives like the Soil Conservation Service to prevent future disasters.
