Dust Bowl

The 1930s are known as the Great Depression, which was sparked by the stock market crash. The crash was exacerbated by environmental damage in the mid-west. 

When homesteaders settled the Great Plains, they disturbed the dirt and removed the natural grasses. This made the land susceptible to dust storms. However, the problem was increased due to a drought. 

Dust storms grew to enormous proportions and caused health problems, even resulting in death. In May 1934, a two day dust storm occurred on the Great Plains, which was one of the worst dust storms. 

April 1935, a Black Blizzard occurred, giving the day the nickname "Black Sunday." The conditions in the mid-west became so bad that people had to leave.
