In this March 25, 1935 file photo, children cover their faces during a swirling dust storm while pumping water in Springfield, Colo. The Dust Bowl was manmade, born of bad farming techniques across millions of acres in parts of Texas, Oklahoma, New Mexico, Colorado and Kansas. Now, even as bad as the drought is in some of those same states, soil conservation practices developed in the aftermath of the Dust Bowl have kept the nightmarish storms from recurring.
