GRAND FORKS. N.D. – Strong winds ahead of a severe winter storm picked up countless tons of topsoil and carried them east into Minnesota. It was like a blinding wall of dirt.

Red River valley. Meteorologsts use the Sahara term “harmattan” for cold, dry dust storms in seasonably stressful seasons. North Dakota farmers call them Black Devil winds.
