The morning of January 12, 1888, was unusually mild, following a punishing cold spell. It was warm enough for the homesteaders of the Dakota Territory to venture out again, and for their children to return to school without their heavy coats --- leaving them unprepared when disaster struck. At the hour when most prairie schools were letting out for the day, a terrifying, fast-moving blizzard blew in without warning. Schoolteachers as young as 16 were suddenly faced with life and death decisions: Keep the children inside, to risk freezing to death when fuel ran out, or send them home, praying they wouldn’t get lost in the storm.
