So, is this weather, or the result of a war with the land? Literally tons of soil blew east from the centre of North America dropping on the east coast and the Atlantic Ocean during the 1930s: a drought combined with very poor farming practices that stripped the prairies of the indigenous grasses that held the soil and moisture in place with their roots.
It made excellent mulch, evidently. Of course it would; fine topsoil, perfect for planting seedlings. The process of getting it spread all over your fields however was catastrophic.
