The fountain in Chicago's Grant Park will be turned on at 11 a.m. on Thursday. It operates from 8 a.m. to 11 p.m. through the fall, depending on the weather.
During the season, the fountain, at 301 S. Columbus Drive, puts on a display every hour on the hour with water that shoots 150 feet in the air. After dusk, the display is accompanied by a 20 minute light and music show.
The fountain is run by the Chicago Park District through a partnership with March of Dimes and Kmart.
