Snake through Marquette Park

Marquette Park, originally called Lake Front Park, is a municipal park completely surrounded by Indiana Dunes National Park. Its primary elements include 1.4 miles (2.2 km) of white sand Lake Michigan beaches, inland ponds, impressively high sand dunes, wetlands, a lagoon, and indigenous oak savanna.

The Grand Calumet River is a 13.0-mile-long (20.9 km) river that flows primarily into Lake Michigan. Originating in Miller Beach in Gary, it flows through the cities of Gary, East Chicago and Hammond, as well as Calumet City and Burnham on the Illinois side. The majority of the river's flow drains into Lake Michigan via the Indiana Harbor and Ship Canal, sending about 1,500 cubic feet (42 m3) per second of water into the lake.

Gary Bathing Beach Aquatorium, formerly known as Lakefront Park Bathhouse and also known as Chanute Aquatorium, is located at One Marquette Drive at Miller Beach in Marquette Park, Gary, Indiana. The aquatorium was designed by George Washington Maher and constructed in 1921. It was listed on the National Register of Historic Places on November 25, 1994.

Indiana City was a notional community in northern Lake County, Indiana, at the mouth of the Grand Calumet River. It was located in present-day Marquette Park in Miller Beach, near the southern tip of Lake Michigan. Indiana City was one of a handful of early contenders to be a port city on southern Lake Michigan, alongside Chicago, City West, and Michigan City.
