About this map

Indiana Dunes National Park dominates the northern shoreline along Lake Michigan, preserving the distinct ridge-and-swale topography including the Tolleston Dune Trl. This industrial and recreational landscape is defined by the heavy footprint of Midwest Steel near Burns Harbor and the expansive rail infrastructure of CSX Transportation moving through Portage and Willow Creek.

Genealogical and local history markers are prevalent throughout the residential developments, with several dedicated sites such as the Temple Beth El Cem of Gary and McCool Cem. The map illustrates a complex water management system where the Little Calumet River and Deep River are augmented by numerous man-made channels like Crisman Ditch and Robbins Ditch, reflecting the long-term engineering of the Calumet region to support both industry and suburban growth in places like South Haven and Hobart.
