The range of motion at the shoulder may be limited by pain. A painful arc of movement may be present during forward elevation of the arm from 60Â° to 120Â°. Passive movement at the shoulder will appear painful when a downwards force is applied at the acromion but the pain will ease once the downwards force is removed.
The rains helped to end the Great Depression. (Sources: Drought in the Dust Bowl Years, National Drought Mitigation Center. Farming in the 1930s, Living History Farm.) For more, see Timeline of the Great Depression.
Technically, the driest region of the Plains â southeastern Colorado, southwest Kansas and the panhandles of Oklahoma and Texas â became known as the Dust Bowl, and many dust storms started there. But the entire region, and eventually the entire country, was affected. The Dust Bowl got its name after Black Sunday, April 14, 1935. More and more dust storms had been blowing up in the years leading up to that day. In 1932, 14 dust storms were recorded on the Plains. In 1933, there were 38 storms. By 1934, it was estimated that 100 million acres of farmland had lost all or most of the topsoil to the winds.
