Forty-one iron-ore miners drown or are fatally buried in mud and seven more escape by climbing a ladder during the Milford Mine Disaster, which occurs north of Crosby on the Cuyuna Range in northern Minnesota when a nearby lake suddenly empties into an underground mining operation. A county inspector, who had visited the mine the week before the accident, would later state that every precaution had been taken and that the flooding was unavoidable.
