Dust Bowl

from 1930 to 1936

The Dust Bowl was a period of severe dust storms that struck the Great Plains of the United States and Canada during the 1930s, particularly in the southern plains in Oklahoma, Texas, Kansas, Colorado and New Mexico. Years of drought combined with the deep ploughing of native grassland, which had held the soil in place, left the land bare, and strong winds carried the topsoil away in huge black clouds. The worst storm, on 14 April 1935, called Black Sunday, darkened the sky across the region. Tens of thousands of families left their farms, many moving west to California, an exodus described in John Steinbeck's The Grapes of Wrath. The federal government created the Soil Conservation Service and promoted new farming methods.
