Out in W Texas - in the 50's and early 60's before proper plowing and other land conservation measures came about we had bad sandstorms.
I remember one where it lasted 3 days. Others where it was so dark the street lamps would come on. Folks living by cotton fields would have as much as 3 feet of sand deposited in the wind side deadzone of their yard. What would happen was the house blocked the wind and formed a relatively dead air speed pocket on the wind side. Sand trickled down to form long 1 to 3 feet ribbons of sand in the deadzone.
