Neighbors Laughed When He Built a Box Around His Cabin — Until the Blizzard Hit

Discover the remarkable true story of how a single, mocked construction decision saved lives during one of the harshest winters in American frontier history. In 1886, Norwegian immigrant Gunnar Thorsen shocked settlers in Wyoming Territory by building a second structure completely around his cabin, leaving an empty eight-foot gap meant to block the wind. Neighbors laughed, calling it wasteful and foolish—until the catastrophic Great Die-Up Blizzard of 1887 struck with extreme cold and hurricane-force winds. As standard cabins failed, filled with snow, and left families freezing to death, Gunnar’s strange double structure transformed into a life-saving fortress, stripping the wind of its power and preserving warmth inside. While dozens across the territory died, Gunnar’s “box around a cabin” sheltered thirteen people and proved that wind, not cold alone, was the true enemy. This documentary reveals how forgotten Old World knowledge, dismissed as madness, became the key to survival—and how the man everyone laughed at was the only one truly prepared when the storm came.
