The Grand Calumet River and Little Calumet River define the industrial and residential corridors of Northwest Indiana in this detailed survey. While the northern reaches show the infrastructure of East Chicago and Gary, including a slag dump and the Indiana East-West Toll Road, the southern landscape transitions into the preserved wetlands of the Indiana Dunes National Lakeshore. The map documents a densely developed suburban network where Highland, Griffith, and Munster coalesce around historical rail grades and drainage projects like the Cady Marsh Ditch. Local history is anchored by numerous institutions, from the Purdue University Calumet Center to a high concentration of parish schools and cemeteries such as St Johns Cem and Ridge Lawn Cemeteries, reflecting the deep-rooted community character of Lake County.
