The Dust Bowl of the 1930s lasted about a decade. Its primary area of impact was on the southern Plains. The northern Plains were not so badly effected, but nonetheless, the drought, windblown dust and agricultural decline were no strangers to the north. In fact the agricultural devastation helped to lengthen the Depression whose effects were felt worldwide. The movement of people on the Plains was also profound. Poor agricultural practices and years of sustained drought caused the Dust Bowl. Plains grasslands had been deeply plowed and planted to wheat. During the years when there was adequate rainfall, the land produced bountiful crops. But as the droughts of the early 1930s deepened, the farmers kept plowing and planting and nothing would grow. The ground cover that held the soil in place was gone. The Plains winds whipped across the fields raising billowing clouds of dust to the skys. The skys could darken for days, and even the most well sealed homes could have a thick layer of dust on furniture. In some places the dust would drift like snow, covering farmsteads. http://www.weru.ksu.edu/vids/dust002.mpg http://www.usd.edu/anth/epa/dust.html in the lower left you can see the effect of what sunlight that made it through giving and orange appearance to the ground thanks for viewing and any comments.hoping you have a week that is enjoyable to you My brother called me last night and told me his wife's transplanted stem cell treatment has begun producing white blood cells. her count yesterday was 800 and the doctors are elated with her progress
