1860 tornado

On Sunday, June 3, 1860, a tornado struck Camanche. Few buildings were left standing, and all structures were badly damaged. The storm moved at 50 mph. The lack of an organized way to report weather events left people living along the Mississippi River vulnerable. A raft carrying 26 men was hit outside Camanche, and only three on board survived.^[6] The tornado killed a total of 92 people, including at least 41 in Camanche. The outbreak as a whole killed more than 140 people in just a few hours and injured over 300.^[7][8]
