Creston, a city and the county-seat of Union county, Iowa, U.S.A., about 60 m. S.W. of Des Moines, at the crossing of the main line and two branches of the Chicago, Burlington & Quincy railway. Pop. (1890) 7200; (1900) 7752; (1905, state census) 8382 (753 foreign-born); (1910) 6924. The city is on the crest of the divide between the Mississippi and the Missouri basins at an altitude of about 1310 ft.—whence its name. It is situated in a fine farming and stock-raising region, for which it is a shipping point. The site was chosen in 1869 by the Burlington & Missouri River Railroad Company (subsequently merged in the Chicago, Burlington & Quincy Railroad Company) for the location of its shops. Creston was incorporated as a town in 1869, and was chartered as a city in 1871.
