This was the easternmost of four corrugated metal grain bins on the south side of the violent Spencer tornado‘s 1/2-mile-wide circulation. The one at left, the middle bin, and its western neighbor, were at least half full, and stayed onsite, albeit strongly deformed in places. The western bin (almost no grain, not shown) and this one (very little grain) came off their moorings. Attachments are evident roughly every 6 feet; but the lack of grain made for little or no extra support. The bin blew north and flipped onto its roof.
