This long-lived (over half an hour) tornado was obviously well-organized and probably quite intense at times, capable of great damage to a populated area. During its early, smaller stage, the vortex flipped a vehicle on I-80, injuring two kids, and destroyed some unanchored mobile homes. Fortunately, the tornado missed nearby settlements, passing over open farm and ranch land as it briefly developed concentric vortex tubes, then grew stouter (shown in this scanned film slide, in the shape of a thick stovepipe).
