It was an uncharacteristically sunny day in the small town of Minneapolis. In the 41 years since the Dakota Indians had been expelled from the state of Minnesota, the town had developed into a center for logging and milling, harnessing the power of the mighty Mississippi River. The Minneapolis milling industry was profitable, but dangerous. The river gives life and power, but it is unpredictable and uncaring. The collapse of the Eastman tunnel caused the banks of the river to erode, leading to several buildings sliding into the torrent. An explosion of flour dust at the Washburn Mill, owned by the company that later became General Mills, killed 18 people and scattered debris over 8 city blocks.
