On June 8, 1966, Topeka was struck by a tornado rated F5 on the Fujita scale. It started on the southwest side of town, moving northeast, passing over a local landmark named Burnett's Mound. According to a local Indian legend, this mound was thought to protect the city from tornadoes if left undisturbed. A few years prior to the tornado strike, development began near the mound, including a water tank constructed near the top of the mound against the warnings of local Native Americans. The tornado went on to rip through the city, hitting the downtown area and Washburn University. Total repair cost was put at $100 million, making it, at the time, one of the most costly tornadoes in American history. Even to this day, with inflation factored in, the Topeka tornado stands as one of the most costly on record. It also helped bring to prominence future CBS and A&E broadcaster Bill Kurtis, who became well known for his televised admonition to "...take cover, for God's sake, take cover!" on WIBW-TV during the tornado. (The city is home of a National Weather Service Forecast Office that serves 23 counties in north-central, northeast, and east-central Kansas).
