About Barnum

Barnum is a city in Webster County, Iowa, United States, just off U.S. Route 20. The 2020 census counted 175 residents. Barnum lies at the southeastern margin of Manson crater, an impact structure buried by glacial till and outwash. The district was established on July 1, 1993, with the merger of the Manson and Northwest Webster districts. The short version is that Barnum carries an earlier story into the places people know and use now. That is the local read on Barnum: its past remains attached to the places people use now.
