We had one like that in February 1978 in Saskatchewan. It started blowing on Sunday and didn't let up until Thursday. The wind had 400 miles of bald prairie to blow across with nothing to slow it down until it hit the hangar line. The drifts in front of the hangars were 20 feet tall and hard enough to walk on without sinking in. Obviously all flying was shut down for the duration, but the civilian staff still had to come out to the base to cook in the mess halls. They drove from town by driving from one painted dash on the highway to the next. Once the wind finally stopped blowing, it took them two days with front-end loaders and a fleet of dump trucks to clear the ramp area.
