There is no weather more emblematic of the northern plains, and none more dangerous, than the blizzard. It is not merely a heavy snow; the true blizzard is defined by wind — a howling gale that drives the snow horizontal, drops visibility to nothing, and can turn the short walk from house to barn into a lethal ordeal in which a person may become hopelessly lost within a few steps of the door.

A Whiteout at the Doorstep

The old settlers knew the danger intimately, and the stories of ropes strung from house to barn so a farmer could find his way through the white are no exaggeration but plain survival. Livestock drift before the wind and pile against fences; travelers stranded on the highway are counseled to stay with their vehicles rather than wander into the storm.

From the almanac's reckoning:

• A blizzard is defined by wind and low visibility, not snowfall alone.
• Settlers strung ropes from house to barn to navigate the whiteout.
• Stranded travelers are advised to stay with their vehicles.

Modern forecasting gives warning the pioneers never had, but the blizzard has lost none of its power to shut down a region in an afternoon. The almanac counsels every plains household to lay in supplies before the winter and to respect, always, the storm that can erase the world in white.
