Boone, city, Boone county, central Iowa, U.S., just east of the Des Moines River, 15 miles (25 km) west of Ames. Founded in 1865, it was originally called Montana but was renamed (1871) to honour Captain Nathan Boone, son of frontiersman Daniel Boone. The railroad arrived in 1866 and contributed to the town’s growth. With the annexation in 1887 of adjacent Boonesboro (established 1851), it became the county seat. Boone Biblical College was founded in 1891 and the Boone campus of Des Moines Area Community College in 1969.
The city’s economy is sustained by agriculture, railroads, and light manufacturing. Mamie Dowd Eisenhower, wife of Dwight D. Eisenhower, was born there, and her birthplace has been restored as a museum. Ledges State Park is 4 miles (6 km) south. The Kate Shelley Memorial High Bridge, just to the west across the Des Moines valley, is one of the highest (185 feet [56 metres] above the river) and longest (2,685 feet [818 metres]) railroad bridges in the country. The Boone & Scenic Valley Railroad operates steam and other trains from Boone to Fraser (northwest) and has a railway museum. The annual Pufferbilly Days festival in early September highlights Boone’s railroad heritage. Inc. town, 1866; city, 1868. Pop. (2000) 12,803; (2010) 12,661.
