Moonrise over Lake Michigan
Chicago's 18-mile Lakefront Trail follows the Lake Michigan shoreline on the city's eastern edge — the side of the sky where the Moon rises. From the lakefront parks and beaches a rising Moon can appear over open water close to the calculated time; inland, buildings hide it for longer. The calculation uses the city reference, 41.85° N, 87.65° W, with a flat horizon.
