Father and sons walk through a dust storm in Cimarron County, Okla. (1936) Steinbeck writes: "The dust was evenly mixed with the air, an emulsion of dust and air. Houses were shut tight, and cloth wedged around doors and windows, but the dust came in so thinly that it could not be seen in the air, and it settled like pollen on the chairs and tables, on the dishes." (Library of Congress)
